I can't see what any of the issues are.
When I used to be a PC gamer (pre-steam's preloader) I would have to INSTALL the game before I could play it. If i ran out of space on my HDD I would either uninstall a game or buy a new HDD. So everyone moaning about that is clearly nuts or under 20.
Installing onto the Xbox 360 & PS3 is optional and i presume a minority used it, but having it mandatory for the next Xbox isn't a deal breaker, it bares no impact on my gaming experience and entertainment. thats why i buy a console to get entertainment. If it loads quicker then its great. I can't see how this is a negative point at all.
Consoles should have the ability to pop in a disc and play without any PC-like system set up. It seems the Nextbox will have something along these lines, but it still requires an install behind the scenes. Installing the game does have advantages, but with proprietary HDDs and limited space, install swapping is more than a fringe concern. And it something that should NOT even be in the picture. It's not a problem on PCs because people can get large, inexpensive HDDs from where ever they want. That is not the case with consoles.
Always on/connected - Not an issue, my pc/laptop is always connected to the internet when its turned on, and my 360 automatically connects to Xbox Live. Can't really see how thats an issue? As long as the DRM thats implemented isn't invasive in any way and detrements my gaming experience then I couldn't care less.
Your last sentence in that paragraph is the crux of the issue. Anyone who thinks the "always on, always online" is not DRM is fooling themselves. It is going to prevent used games and will most likely prevent offline play in order to stop piracy. (which of course won't work, and it will only affect legitimate customers as usual) As long as we can play our games offline when our internet decides not to work, then I'm fine with the always online "feature" too. However, this feature is still too vague so we will have to wait for specifics.
Kinect bundled with the Xbox and being required to plug in? - Great! I've always toyed with the idea of getting a Kinect but never got round to it. Having it with the new xbox means devs can integrate it more and actually make it worthwhile to have. Yes having it plugged in as a requirement is a pain but get over it. As yet we don't know why thats required or what they intend to use it for other than the obvious so any comments really are uneccesary until we at least know more.
Kinect is, and always will be, a gimmicky piece of hardware that no "true" gamer will want or need. Visual gestures and voice commands won't add any tangible value to typical games; and it will only ever be truly useful in dancing/exercise games. And it has already impacted those who don't want it because of the changes to the 360 dashboard. The nextbox requiring
that it be plugged in is evidence that it's going to be a big part of the console's user experience which is not exciting for those of us who don't want it. Again, a feature like this should be optional.
