Better still, it requires fewer resources than Windows 7, which is kind of crazy. Which all sounds great. And sort of what I expected. What sounds (and looks) a little dicey is that the awesome, modern tile UI is basically just a skin over Windows. The rest of the "classic Windows desktop" is still there, looking underneath, albeit adjusted to be more touch friendly with "fuzzy hit targeting," so regular Windows applications will work with touch or keyboard/mouse. But the two things together looks like a miscreant experience, even in Microsoft's demo. The idea of running real, full Windows apps on a tablet (or anywhere) isn't a bad one, but it looks pretty gross and weird in practice.
We'll apparently see a lot more in September at Microsoft's Build conference.
