From the video:
"[The apps] are designed for touch... but of course they work well with mouse and keyboard as well if that's what you have."<p>Sorry, but that's not how it works. Microsoft needs to realize this. Everything he was doing there would be <i>terrible</i> with a mouse.
The main problem I have with this is the same problem I have with the horrible Xbox dashboard - The left to right sliding tiles hurt my eyes like crazy. It's like trying to look out a side car window as you are travelling along and your eyes don't know what to focus on. At least the old Xbox dashboard tiles lined up behind each other so your eyes were always in the middle of the screen, but with this, ugh my eyes hurt just watching the demo.
Do they expect the enterprise to flock to this? As a nerdy consumer, I love that they're moving forward on UI, but as someone who deals with end users, this is going to scare the shit out of people. I don't see a start button anywhere in those screenshots.
