I like it. Nearly all the features shown off in that video make me go "want!". The additional start screen organizing features are precisely what i'm looking for.

Now all I want is more and better fullscreen apps. Not the "your favourite news source" apps. They're bullshit on phones and they're even more bullshit on PCs or big tablets. Real, useful apps. Like a barebones spreadsheet that fits in a sidebar. Zen-writing text editor. Extensions for IE-in-fullscreen-mode. Music player that doesn't suck and doesn't want to be all "cloud".

They're getting real close here. I really hope app vendors follow suit.

(p.s. if you try Win8 without a touchscreen, you didn't really try it at all)
