I'm always confused by those people complaining about not being able to use it as a desktop system.
I literally spend all my time on the desktop in the CP. My metro start screen appears for about a quarter second it takes me type in the first few characters in whatever I am trying to launch and disappears. More often than not it doesn't even have time to render.
I don't understand why it is that people feel it's such a step down given my usage hasn't changed in the slightest (except I have pinned remote desktop instead of using the jump list in the start menu).
This is why all of the anti-8 sentiment confuses me so.
Because Metro is not about a start screen, it's also about window management. Something that you can kinda get around in Windows8 but that's intended to become the standard in future Windows releases.
I could stand a fullscreen start menu if it was all about that (heck I'm enduring Gnome Shell's Overview right now, which even while offering a lot more features than Metro is still a fullscreen menu anyway), but the limitation of a few hardcoded window arrangements (fullscreen, 50/50 and 80/20 splits) is something that just won't work for me.
Then Windows8 happens to feel half backed, and not just because of the "beta" status. It neither here nor there when it comes to window management, offering a weird mix of behaviours depending on the type of app you are running.
You could stick with the classic desktop, but then where's the advantage of running Windows8 at all? There might be some improvements under the hood, but at the end of the day you have the same experience as with Windows7 plus a few annoyances, and you end wasting time adapting your workflow to work around features you aren't using.
The start menu... I didn't like Windows7 start menu so it's not like I'm attached to anything. I disliked it same as I didn't like it when other desktops like KDE adopted it. The old "classic" start menu wasn't good either, but at least it wasn't such a mess that you absolutely needed a search box to find anything.
If we really want to go that way I'd rather use something like Synapse and be able to find not just my apps but absolutely everything on my systems from a single search box, and then drop the whole menu instead of pretending that the new implementation is of any actual use other than wasting space.
Also the widgets on the start menu could be a nice idea wasn't it because I'm working on my desktop, not on the start menu. I can already get info about incoming mail, weather, chats (which I can reply to without even opening new windows or changing my window arrangement), calendar events and what not without touching any key, so I don't feel any need for a whole new screen full of gadgets.
Summing up, I don't see Windows8 adding anything I need, yet it would force me to change my workflow for no good reason. The Metro style window management feels like a huge step backwards if you are doing anything other than watching movies or browsing the web. I just can't get my work done with those crappy split options.
