Challenge your own assumptions and look at the bigger vision behind the whole thing. Then you will understand both why Metro will work on the desktop and why it will change the way people use PCs.
Christ this is such meaningless pap. "Challenge your own assumptions and look at the bigger vision" - jesus. WHAT vision for pete's sake? The vision of taking a 30% cut from every commercial app that wants to be done in Metro going forward? They've released the dev preview to the public and provided anonymous commenting on their blogs for a reason.
The continual defense that "It's a DEV preview! Relax" make absolutely no sense in light of what we've seen and how MS has presented it thus far. Their "vision" as presented by the dev preview is schizophrenic. We're being told "No compromises!" but when you actually use it you'll find that's far from the truth.
If you truly believe switching to a full-screen menu that resembles a completely different OS to just launch a * desktop program constitutes 'vision' then I really don't know what the hell to say to you. The people I've shown Win8 to at the Office are just baffled (other than commenting on how incredibly ugly it is - man will MS ever hire some decent designers? How could those search Start screen examples ever be considered less than horrific by any adult who's used a modern GUI in the past decade?)
Of course there's more to WIn8 that Metro, albeit from the blogs it's hard to tell (oh wait - Explorer ribbon! New task manager! Woohoo, get my checkbook!). But the interplay between Metro and Desktop is the #1 interaction that most users will have, and from my befuddled users and the many commentators on blogs and articles, the popular reaction seems to be "WTF?!".
