Thanks to TheRPG for opening my eyes on this subject.

After testing Vista now on two 100% identical machines for close to 48 hours I have discovered that by having superfetch set NOT TO monitor at start-up makes a big difference on a Vista PC while it?s booting up.

I started off with two identical almost bare (only basic software installed) Vista machines. One with superfetch enabled at boot-up & the other without. In the beginning they both loaded quickly and there did not seem to be any difference in boot up speed, if anything the superfetch enabled machine was a little quicker.

But then I started loading programs, Zip & RAR, Antispyware, Limewire, ATI drivers, NOD32 etc, on each machine and I noticed the more I loaded the machines up with programs the slower the enabled superfetch PC became with each boot-up.

I eventually loaded 43 programs on each machine and this is what I discovered:

The time it takes for the system that has the superfetch set NOT TO RUN AT BOOT-UP is twice as fast. This tweaked system now gets to the stage where you can actually start to use the PC and go online nearly 35 seconds quicker than the identical machine that is still superfetching at boot-up. I must stress that they are both identical ASUS OS's running the exact same setups and installed programs.

Now getting back to my Personal Home machine which is a DELL, here are the results:

Before I turned off superfetch to load programs into my system at start-up, Vista would boot up to my desktop very quickly, but then it would just hang for about 2 minutes while superfetch loaded everything. The programs it was superfetching where totally unnecessary, (get a freeware program called "autoruns" by Sysinternals and quickly run it to monitor what superfetch actually loads at start-up) You will then understand what I am talking about.

Registry settings to turn off superfetch at boot: (taken from TheRPG's post)

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters]

"EnableSuperfetch"=dword:00000002

"EnablePrefetcher"=dword:00000001

Since turning superfetch off at boot up by changing the Reg settings this 2 minute limbo has stopped without any notable side effects to anything else.

Superfetch still works but only after the PC has booted, and the prefetch still loads the essential goodies at start up like it did in XP.

The things you have to take into account here is that Microsoft would have tested Vista with only a few "if any" programs installed onto their OS's at Redmond, and in that scenario Vista still boots up quickly with superfetch enabled at startup.

But once you start to load lots of programs onto Vista having the Superfetch running at boot up actually slows down the start up process.

Typically the Microsoft Gurus would not have seen this in their tests on their own machines and for that reason they did not pay much attention to the Beta Testers reports because they (Microsoft) would not have been able to duplicate the problem themselves with just a handful of programs running on their Vista's.(And I know there was quite a few Beta testers having concerns with Vista's slow start-ups)

Now this tweak has not slowed down anything else on my machine.Nothing is actually disabled, settings have just been changed for the better. Programs still open as fast or maybe even faster than they did before. Overall the performance of all 3 PC's I tested has increased.

I know some of you will dispute this info and that is OK as well, but the facts speak for themselves.

Now go forth and plagiarize

I've never experienced anything that could be described as a "hang". My ageing PC allows me to do anything I want whilst Superfetch is working away in the background. :huh:

I have the superfetch enabled and Vista is faster than XP:

the boot is faster than XP;

the desktop is faster to become ready than XP, it's more responsive and so I can start working as the desktop is shown;

the applications are loaded faster than XP

My PC is old: P4 1.7GHz, 768MB RAM, Geforce 6200 AGP 256MB.

same here, my pc boots just as fast as XP, when I first log in prefetch does it's thing for a minute or so but my computer doesn't slow down at all while it's doing it so it doesn't really matter to me. My applications load faster than in XP also.

Is this the supposed conclusion? Do you have a source to back up these statements or did you make them up?

It's a trade off. If I disable Superfetch, the minute or so of horrible lag after a reboot is gone, but word, IE, etc. all take longer to load.

Since I so very rarely reboot, it's a no brainer: leave it on.

Not really if you system is on Raid 0 configuration. Then Superfetch has no meaning....

my Vista boot time is definitely slower than XPs was. After the scrolling status bar goes for a few seconds, the screen goes black for around 20 seconds, then the circular windows logo pops up and it finally boots to the desktop.

i'll play around w/ this setting and see if it does anything for me.

Not really if you system is on Raid 0 configuration. Then Superfetch has no meaning....

Not quite. Even the fastest HD/Raid combination in the world still is slower than something precached in memory. Superfetch always provides a benefit, even if you THINK it doesn't.

Not even close to accurate. NO drive array, raid 0 or otherwise, is even close to the speed of the RAM in your system.

drives are an order of magnitude slower.

The thing is that superfetch doesn't load let's say a complete game in a RAM. It does load something, but it has almost no meaning if you run Raid 0 configuration.

With superfetch or without your computer still needs to load the game from hard drive, and that's the point. I'm not sure what is happenning as you add more and more memory. I guess Superfetch loads more 'garbage' from hard drive to Ram.

I run Vista X64 with 4GB and memory usage when the system idles is 39%.

Here is some fact. A lot of CPU and Hard Drive and Ram time are wasted by Superfetch. Why? Well, Superfetch has to load the data from hard drive into RAM, which your computer will do it anyway when you start app/game. The data are not coming from nowhere but from hard drive into RAM, which means hard drive has to spend equal or same amount of time as it Superfetch is disabled. Now you can waste a lot of CPU, Hard Drive, Ram time cause Superfetch loads up the thing you're not gonna even maybe use.

I look at Superfetch as software version of hardware solution for this problem, and that's OS in ROM chip which loads up instantly and that's the future.

YOU WRONG!

Superfetch learns which applications and data should be kept in memory, superfetch assigns a priority to memory's pages.

Without Superfetch, the applications and data are stored in memory in a "flat" way like in Windows XP, they haven't a priority, and so the memory managment is not able to learn what are the best programs and data it should keep in memory, it's not able to learn which programs and data should unload from the memory. Without Superfetch your hard drive activity is increased because the right programs and data are not found in memory, they are unloaded without any intelligent criterion and this means your hard drive has to reload them.

Without Superfetch the programs are loaded and unloaded in a raw way, causing a lot of hard drive activity because you lose the low I/O priority feature for loading/unloading memory's pages.

Again, you are incorrect. No drive, SCSI, SATA, PATA, or Raid array is faster than RAM, and will not be for the foreseeable future. Robson/hybrid drives and solid state drives moves it forward, but still an order of maginitude exists between the speeds.

A decent 7200 RPM PATA drive with Superfetch on a reasonably profiled machine will seem much more responsive than a 15000RPM RAID0 array without Superfetch, until your usage falls well outside the profile.

With superfetch or without your computer still needs to load the game from hard drive, and that's the point.

The point is, if you can have half the game's dlls loaded in precache before you even launch the game, half the loading is already done.

I'm not sure what is happenning as you add more and more memory. I guess Superfetch loads more 'garbage' from hard drive to Ram.

If the programs you run on a daily basis are garbage, then your assumption would be correct.

I run Vista X64 with 4GB and memory usage when the system idles is 39%.

What an incredible waste of RAM.

Most likely they are running a fast enough system already that compensates any slowdowns or sluggishness. So it wouldn't matter if they were running XP, Vista or any other OS because they would most likely not notice any slowdown.

Ok, now on to Superfetch the greatest thing ever, loads apps faster by caching them into memory supposedly. Ok if Superfetch was so magnificent then why is my whole Vista UI completely sluggish and unresponsive? Now supposedly if you run a memory demanding app, close it and open another app, it will load much faster compared to XP or with Superfetch disabled. Even if you're not running any apps at the time it will load things faster compared to XP or with the feature disabled.

Mind you my PC is Vista Premium/Ultimate Ready/Capable, Dual Core AMD64, Graphics card sucks, well sort of low end geforce 6150, however can play Lost Planet: Extreme Condition fine on the absolute lowest settings Albeit significant slowdown in large areas or action on the screen. Should run the Vista UI fine since I can play this without any real slowdowns or sluggishness, right? Well wrong, the Vista UI is extremely sluggish for me even with the performance & reliability packs, taking longer than XP to load anything, browse folders/control panel, sluggish effects. Some programs don't kill properly by the task manager sitting there eating memory. Network connectivity problems, I'll start downloading then wireless signal will cut out crippling the network until I unplug/replug in the router. Many more as well in the way of compatibility, sluggishness/performance problems as well.

Now on to what I've experience using Vista for a while, apps do not load any faster than XP. In fact they are 2x slower than if I did the same thing on XP, completely sluggish to hell. Apps that I load after closing a game, load slower than if If I opened them before using any other programs/games.

Sorry, but this is a joke to me that I can't believe you fell for it especially since it's coming from Microsoft, a lying, deceptive, greedy, evil monopolistic company which steps over it's customers, squashes the little or middleman (Competition) with it's corporate greed. Threatens bogus lawsuits (Linux) with proclaimed IP infringement without valid proof although they incorporate ideas in their OS from other OS's. When asked to present code to study as a means of aforementioned possible infringement they refuse with closed source or whatever argument they use to avoid possible suits. Incorporating Intrusive DRM/WGA and activation which in the end is a hassle for legit consumers since pirates are happily using their cracked, DRM/Wga, and activation free copies of windows without worries. Is trying to eliminate linux by bogus claims, getting them to jump ship or pay them a royalty like fee for unproven IP infringement. Also they basically treat everyone as a pirate by forcing Wga/Activation and DRM. Also in the past the OS had tons of security flaws, where even browsing the web can get you a nasty Trojan or Virus, the OS that crashes a bit to much. The company that has a poor track record, monopoly lawsuits or lawsuits and much other concerning behavior.

Finally in Vista they are starting to do something right, but it's a Far cry than what they could be doing with the OS if they just listened to the consumer, what they do/don't want (Less Intrusive/No DRM or WGA), No hassle with Activations. People are going to pirate regardless of what schemes are in place and will find a way to avoid it So what's the use?

I'm not bashing Windows, even using Vista/XP myself legally bought in a dual-boot config. I was just trying to say, take anything Microsoft says with a grain of salt due to their past record/history. I thought my Experience with Vista would be WoW, but so far it's been Meh.

Although if my or any Games/Apps had 100% compatibility with Linux, I wouldn't hesitate and would switch completely in a heartbeat. :p

Ignore the consistency or coherency and spelling/grammar of my comment, as it's almost 3am EST here where I live and I'm dead tired.

G'Day and Night. :sleep:

Removed certain phrases.

Xtreme2damax, so you wanna explain to me why my system still runs fast and load everything fast EVEN when my settings are in power saver WHICH UNDER CLOCKS my CPU to 800MHz. My spec are as follows:

Laptop

C2D T7300 2GHz

2GB RAM

Intel X3100 graphics card (3.5 WEI)

200GB HDD

OR Anyone wanna explain WHY MY SYSTEM LOADS APPS FAST and browsing the internet with NO LAG before you guys talk more **** about vista.

has it not occurred to you, that your setup has serious issues? you really think vista performs as badly as that for everyone and we're just lapping it up? please. :rofl:

so your pc is vista certified? complain to your oem. they're the ones at fault here.

just for the record, i'm running vista on a somewhat decrepit old s478 mobo (asus p4c800e dlx). that's 4 years old now. my cpu is a pentium m which is well over 2 years old. single core, 32bit only, 1.7ghz..... vista absolutely flies on it. admittedly i have 2gb of ram. i do concede vista needs this amount to function properly. and i have just the one single sata hard drive. running vista, my pc is much faster than xp for launching applications/browsing folders/everything. even all my games play just fine. admittedly i haven't bought any new games so can't compare but all my old games like hl2/quake4/gta:sa run at the same settings as i could manage in xp.

as for the 2nd half of your post, have one of these -> :laugh:

Actually, I'm running Vista Ultimate on an Asus A7N8X-E Deluxe with an Athlon 2400+ and 1GB RAM, Radeon 9700 Pro with Aero turned on, and it still manages to perform better than XP. I have some complaints about booting up slowly, and stuff like TrustedInstaller suddenly doing some stuff behind my back (on single-core systems this is still an issue), but then I dualboot into XP and it has just these same problems, + more. Anyhow, I just wanted to mention that it runs fine on 1GB RAM too.

    • <Moved to software discussion and support> I've got fond memories of Winamp. Changing the skins, the different visualisations etc. But now I just need a simple music player. MSN messenger would be another one, MSN Messenger Plus (I think?) offered so many different plugins. But again, it probably wouldn't work for me these days. And then there is miRC. i think it's still going these days, but lord i had fun with that back in the day. Now it's mostly stuff like Discord, WhatsApp group chats, Signal, Telegram... /me is showing his age...
    • ive always been fascinated by old software this is an old video player for windows from apple
    • In the way that you framed it incorrectly. You wrote: "The constant need to close all browser sessions and wait for a new version to install" There's no "constant need to close all browser sessions". That's factually incorrect. The browser downloads its updates in the background and installs them when you open it again. Silently. And there's no "wait for a new version to install", updates are small and take 2-3 extra seconds AT MOST, if any. If you have an SSD, there's zero extra time. Also, every mainstream browser operates this way. Firefox, the FOSS go-to browser, the default on almost every Linux distro, does exactly the same. Also, you don't need to constantly restart Edge for updates to install, you can completely ignore them and it doesn't even ask you to handle them, it's all silent and automatic. So I don't understand what else do you want.
    • DuRoBo Krono Review: Portable E-Ink reader with great ideas that need a bit of improvement by Taras Buria Phone-sized e-readers are gaining traction these days, with more people treating them as a getaway device to cure phone addiction (or at least they are trying to) or having a more pocket-friendly reader that is easier to carry and hold. The market now has plenty of such readers to choose from, and DuRoBo is the latest addition, a new player that offers a more interesting approach to the idea. The Krono is a $279 e-reader with an interesting twist, which tries to make the device more fun and ergonomic. Here is my review. Disclaimer: DuRoBo provided the review sample without any editorial input or pre-approval. The Krono comes in a phone-sized box with pink accents. Inside, you get the device itself, a short user manual, and a USB cable. The cable is a bit old-fashioned, Type-A to Type-C, which is a bit disappointing. Hot take: I would rather have no cable in the box rather than another Type-A cable that gets immediately thrown into my box full of similar cables I never use. The Krono also has no charger in the box, as it relies on accessories you already own, which is fine with me. Here are the specs: Dimensions 154 x 80 x 9.0 mm or 6.06" x 3.15" x 0.35" 173 g or 6.10 oz Materials Black or White plastic Display 6.13-inch E-Ink Carta 1200, 1,648 x 824 pixels, 300 ppi Touch-capacitive. Dual-tone frontlight. Processor 8-core Qualcomm Snapdragon 690 (QTI SM6350) 2 performance cores at 2.07 GHz 4 efficiency cores at 1.71 GHz Memory 6 GB Storage 128GB, non-expandable ~104GB available out-of-the-box Operating system Android 15 with a custom launcher Connectivity Wi-Fi and Bluetooth Battery 3,950 mAh battery Buttons and port USB Type-C port Power button, Volume button, Smart Dial Breathing Lights Audio Mono Speaker and Dual microphones In the box The Krono, a Type-A to Type-C cable, user manual Price $279 on Amazon First impressions Right off the bat, no, this is not a phone replacement. Do not approach this device thinking it can serve you as a dumb phone to cure your TikTok addiction. In addition to the fact that the Krono has no cellular connectivity, I strongly believe that no amount of extra devices can fix your phone addiction until you put some serious effort into it. The Krono is a phone-sized e-reader, a companion for your phone dedicated to reading without distractions. The DuRoBo Krono is made of plastic with a very fine texture. It is hardly premium, but I also cannot say it feels cheap. The device is also a bit thick, quite dense, and well-built without rattling or cracking. You get to choose between two colors: white and black. The front has quite thick bezels, which is hardly surprising for an e-ink device. These things use front light, with LEDs usually placed on the screen perimeter. While I do not mind thicker bezels, the notably larger chin cheapens the look a little. What I mind is a notable seam between the display and the main case, which, after just two days of use, collected plenty of dust and specks. The back of the Krono is what makes the device stand out. There is a cylinder (DuRoBo calls it the Axis) embedded in the back of the reader, housing three elements: a power button on the right edge, a Smart Dial on the left edge, and "Breathing Lights" on the back. An etched DuRoBo logo sits below the cylinder, and it is the only piece of branding you can find on the device. Overall, the design and materials are very unassuming, but the cylinder with additional control elements certainly elevates the look and makes it more interesting. Other physical elements include two microphones (one on the top edge and one on the bottom edge), a USB Type-C port, a volume rocker, and a single mono speaker. There is no fingerprint reader, so if you want to protect your device, a PIN is your only option. The official TPU case is not the most premium-looking Display The Krono has a 6.1-inch E-Ink Carta 1200 touchscreen display with a resolution of 1,648 x 824 pixels (300 ppi). The display is front-lit, and you can adjust the brightness and temperature from cool to warm. Unfortunately, the Krono lacks automatic brightness and temperature adjustments, and you cannot set a custom schedule for the frontlight. However, you can set it to always enable frontlight so that you can see what is happening on the screen when turning it on in a dark environment. On the bright side (get it?), the front light can get extremely dim so that the screen is barely readable in a pitch-dark room. The front light is also uniform across the screen, with no noticeable temperature gradients. I am very susceptible to uneven front light, and it is very easy for me to notice it, but the Krono is doing a very good job in this area. I also like that the edge shadow is not very prominent and barely visible in the black variant. E-Ink Carta 1200 is not the newest generation (there are Carta 1250 and 1300), but it is still a good display. It supports three modes: Clarity, Speed, and Quality. In Clarity mode, text is very sharp and easy to read, but you trade that for more ghosting, a slower refresh rate, and more artifacts when the display changes images. Speed mode, as the name suggests, boosts refresh rate and reduces ghosting, but fine print and text become more jagged. Finally, Quality mode is only available in Android apps. It has the lowest refresh rate, but in return, you get much better visuals, improved gradients, and more. Like brightness and temperature, you can toggle modes from the control center. It is available when swiping from the top-right corner of the screen (the top-left is for notifications). I also like that the Krono can work as a desk clock when not in use. It has a bunch of screensavers, including horizontal clocks with time, date, and current battery level. The screen refreshes once per minute, and battery drain is extremely low (not even 1% in 24 hours). It is a great use of the technology, and another thing I wish more e-ink devices featured. Smart Dial The Smart Dial is Krono's main party trick. It sits on the left side of the device and serves multiple purposes. You can twist or press it to perform various actions, depending on the current use case scenario. When reading books, twisting the dial flips through pages, and pressing it refreshes the screen. On the home screen, the dial adjusts the brightness, and holding the dial pressed launches voice note recording. Finally, a quick double press launches the DuRoBo AI chatbot. While the dial scroll is not notched, it is very smooth and has haptic feedback that confirms your actions, which feels very nice. As a long-term Apple Watch user, I love the idea behind the dial. It feels very natural and oddly satisfying to use, especially with that subtle haptic feedback. I never liked flipping pages with touch input, and I strongly believe each e-reader should come with some sort of physical controls for turning pages. The Krono has both volume buttons (which also work as page turners) and the dial, so you are free to use whichever you prefer. With that said, the dial is not perfect. For one, it sticks out of the case way too far for my liking, raising concerns about durability and longevity when carrying the Krono around in a pocket (it is a pocket-sized device after all). Also, it has too much wobble, which cheapens the experience and makes it feel a bit flimsy and unsecured. While there are two plastic guards on the Krono's case, they are way too small for any kind of protection. I also think DuRoBo should let users customize dial actions (the only available customization is scroll direction), particularly for long and double presses. Not everyone needs voice notes, and DuRoBo AI does not work without an active internet connection, leaving the long press essentially useless when offline. I do not mind these features, and I genuinely think they are useful, but I would rather have the ability to toggle between screen modes, turn the frontlight on/off, or launch my favorite app. I also agree with people on Reddit asking developers to let users adjust the dial sensitivity. I hope this is something DuRoBo can implement with a software update to make the experience more personalized (it is a Smart Dial, after all) and incentivize users to fiddle with the Dial more often. The Dial is a fantastic idea, so please, guys, improve it a little. As for ergonomics, they are mostly fine, but the dial's position may feel a little awkward and way too high. When I use a phone or a phone-sized gadget, I tend to rest one of its corners on my palm for a more secure grip. With the Krono, such a grip is impossible because you cannot reach the dial even with big hands. You have to lower the reader a bit and hold it like a bottle without any extra support for the bottom edge. Such a grip is not necessarily uncomfortable (the Krono is also light enough for it), but it requires a bit of muscle retraining. Sometimes, I do not bother with the dial and hold the Krono like my phone, flipping through pages with volume buttons, as they are perfectly positioned for my right-hand thumb. Interestingly, when testing the Krono, I would often find myself thinking that a roller embedded in the long plastic cylinder on the back of the device would have been a much more comfortable solution. There is a free idea for you, guys. Software The Krono runs Android 15 with a very minimal launcher on top. The home screen presents you with a list of apps, a scrollable list of widgets, and your user profile. Widgets can display time, calendar, or recent books for quick access. You can also add or remove apps from the home screen to keep the most useful stuff around without tapping "Apps." I like this minimalistic approach; it looks clean, easy to understand, and light. I understand that some may find the list of all apps way too clean, but fortunately, DuRoBo lets you switch to traditional icons. The reader also has a bunch of preinstalled apps: Read: The default app for reading. Browser: A Chromium-based browser. Files: A simple file manager. Music: A simple music player. Spark: A voice recorder with transcription support and AI summarization DuRoBo AI: A built-in AI chatbot. Transfer: An app for file transfer over Wi-Fi. If that is not enough, there is the Google Play Store, where you can download all the extra apps you need, alternative readers, podcast apps, chatbots, and more. DuRoBo is not trying to give you an all-in-one device. The standard software experience is quite minimal, which makes it easy to approach and learn. The standard reader supports EPUB, EPUB3, AZW3, MOBI, PDF, TXT, DOC, and DOCX, which is more than enough to let you read most books without third-party software. As for customizing the reading experience, you can select one of five built-in fonts, adjust size and thickness, adjust margins and spacing (only three variants for each), change text alignment and direction, toggle the reading status bar, and switch to dark mode. There is also text-to-speech, which utilizes Android's default TTS tech. While I like the simplistic approach, I cannot help but feel DuRoBo could have made the built-in reader a bit more customizable. However, I am not going to bog down on this, as you can always install any other reader you prefer using the Play Store or by sideloading an APK. Getting books to the Krono is very simple. Given that the device is an Android smartphone without cellular connectivity, you can transfer files via a USB Type-C cable, download them using the built-in browser, share them over Bluetooth, or use cloud storage. My favorite was the built-in Transfer app. It is simple, reliable, and very well-designed. I was surprised by how well-designed the web portal is. It is fast, pretty, and properly categorized. Well done! Once you have your books loaded, you can highlight or underline text, add annotations, bookmark pages, check the table of contents, and ask AI about the selected text. Unfortunately, the Krono has no built-in vocabulary, but again, that is something a third-party reader could fix. Overall, the built-in reader is light and snappy, with just the minimum amount of features for a regular user to enjoy reading books. The Krono has no built-in reading tracking, so stat nerds will have to look for third-party reading apps. However, you can set a daily reading goal, and the reader will notify you when you reach it (for example, one hour). You can also set a reminder to read at a certain time, and when the time comes, the Krono will light up its back LEDs and unlock itself to nudge you. Other than that, the rear LEDs do nothing, not even showing charging progress, which is an unfortunate misopportunity if you ask me. Quirks aside, Krono's Android runs quite snappily and bug-free. Early reviews of the Krono criticized its Android 13-based software quite a lot, but now, the reader runs Android 15, and its software has fixed plenty of initial complaints. I never experienced any issues with built-in apps. AI attempts The DuRoBo Krono comes with a built-in AI chatbot. There is no information on what model powers this thing, but the system says it was "trained by Google." You can launch the bot from the app list or by double-pressing the dial. It works just like any other chatbot, and you can ask it anything by typing or using voice input. The AI saves your chats, and you can rename, export, or delete them. DuRoBo AI requires an active internet connection, and it does not work offline. Its reach and capabilities are also limited. You can only chat in the app and use it in the reader app as a makeshift vocabulary. However, the implementation is kinda awkward. You can only send a selected portion of text to AI without giving it any requests or instructions. I highlighted the word "dumb," and it apologized to me for not being useful. You also cannot ask follow-up questions or send the generated response to a separate chat. The chatbot is also slow, even with fast Wi-Fi, making the overall experience quite frustrating, which makes me again wish for the ability to remap the double press to something else. Spark, the standard voice recording app, also uses AI for note summarization and transcribing. Neither feature works offline, unfortunately. Spark records notes up to 30 minutes using Krono's dual microphones, and you can rename or export notes. Transcription quality is decent, and the speed is alright, but you can find much better solutions in the Google Play Store. What I like about Spark is that transcribed notes are not locked, and you can always type more to elaborate on your ideas, which is handy. Overall, I like that the Krono is not shoving AI down my throat, but to be honest, there is really not that much to shove. AI features here feel raw and need improvements to be more useful. Battery Life Like most E-Ink readers, the Krono has fantastic battery life. Even with a clock as a screensaver, its standby power consumption is incredibly low. And when in use, you can get weeks of reading on a single charge. Without the front light, my unit never sipped more than one or two percent of battery during a one-hour reading session. It was nice to see plenty of battery-related settings. You can limit charging at 80% to protect battery health long-term, check the number of charging cycles, manufacturing/first-time use date, battery health, and the maximum capacity. Additionally, the Krono lets you select what hardware remains enabled when sleeping. This lets you keep Wi-Fi and Bluetooth on (say, if you want to receive notifications, for some reason) and keep audio playing when locked. Turning these features off effectively eliminates any standby battery drain. I left my Krono sitting for 24 hours with a clock screensaver on, and it did not drop a single percent. The pretty big 3,950 mAh battery justifies the device's thickness and ensures you do not have to charge it for long periods. Speaking of charging, it is capped at only 10W, which is a bit disappointing, as getting such a big battery to 100% takes a notably long time in the era of super-fast charging smartphones. DuRoBo Moodi The Moodi is a standalone, optional accessory for your Krono. It is a wireless remote with two customizable buttons that you can use to flip pages, control media, or scroll webpages. The accessory connects via Bluetooth. Despite having a built-in rechargeable battery, it is extremely light. While the Moodi's shape and form factor is not what I would call particularly ergonomic, it is not uncomfortable to hold and use. The Moodi comes with six removable magnetic buttons with various smiley faces. Buttons sit securely, and they have nice-feeling, albeit a little loud, clicks. It is a cute touch that adds a little more fun and character to the device. There is also an accented power button and a single status LED. The latter displays charging status and connection mode. The Moodi supports three modes: Reading: Buttons work as volume buttons, allowing you to flip pages in the built-in reader or other apps that support page turning with volume buttons. Media: Buttons work as skip forward/backward, which is useful when listening to audiobooks, podcasts, or music. Scroll: The third mode lets you scroll pages in the web browser or any other application The Krono properly detects the Moodi and presents you with an on-screen guide when you connect it for the first time (it also displays the battery level). However, you can only change modes by holding both buttons for a few seconds. It is also worth noting that the Moodi works with other devices. I connected it to my iPhone and it let me adjust volume or control media playback. Sadly, the scroll did not work, so you cannot use it to waste time scrolling TikToks. Overall, the Moodi is a cute little accessory, which I can recommend for those who read a lot. It is very useful for remote page flipping when you do not want to burden your hands by holding the Krono all the time. I only wish DuRoBo included a lanyard for the built-in loop. As for the battery life, after using the Moodi for a few days, I only managed to drop several percent of its 90 mAh battery. Despite the small size, it is rated for weeks of use, which is pretty impressive. At $35.99, I cannot say the Moodi is a must-have accessory, but I see the appeal. I prefer using the Krono with its Smart Dial, as I rarely read for more than 40-60 minutes in one sitting. However, if you have a stand and like reading for long periods, the Moodi is the right thing to have. It is a bit more expensive than regular page flippers on Amazon, but it is on par with similar products from Kobo or BOOX. Plus, it has a little more fun to it with removable buttons and better integration into the Krono. Conclusion At the end of the day, DuRoBo Krono is a nice pocket-sized e-reader. Its software focuses on the main things without trying to be everything at once. The smart dial idea is unique and great, and I wish more manufacturers had something similar in their devices. The display is also good, with an even frontlight and "always-on" support. I did not notice any deal-breaking issues with the Krono. However, you can feel that the idea needs some improvements, such as a slightly stiffer dial in a more ergonomic location, perhaps a little more premium materials, and better software customization. I hope the company won't give up on the idea and improve the dial and ergonomics in the second generation.

    • In what way is any of what I said incorrect? To install an update you need to close all browser instances, upping it from once a month to once a fortnight is an inconvenience for users. Particularly when updates don't offer functionality that users want (notably copilot). Security updates should come as they are needed, not on a release schedule
