So, this is the new Start screen for Windows 8. It looks a lot like Windows Phone Live Tiles. And hey, that looks like an app store.
All apps can be viewed in this tile-based UI, which Josh from TIMN says is, "Very impressive. It looks super fast." You can totally see the Windows Phone influence on the interface, from the tiles to the touch keyboard, which even has a "thumbs" mode. (Sinofsky tells All Things D, "We were clearly influenced ourselves by phones.") The animations and gestures and multitasking are all pretty damn smooth looking, as you can see in this demo video (or, you know, up top).
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, though totally baked in and part of the OS. 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. You can't turn either of the experiences off - it's always there. The regular Windows is always underneath the new Live Tile start screen. The Live start screen always is on top of Windows. 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 - in fact, a ubiquitous OS that'll run on any device, perfectly, is amazing in theory - but mixing the two looks kinda gross and weird in practice, so far. Maybe the way Microsoft's gonna translate touch apps to keyboard/mouse and keyboard/mouse apps to touch to achieve this infinite OS will be downright magical in the end. But I'm not seeing this hybrid thing right now, even as impressed as I am by all of the incredibly cool modern interface stuff that's totally designed for tablets. And beyond that, at least when we're talking about tablets, it looks like Windows 8 still has a lot of the rest of the problems that made the current Windows less-than-good as a tablet OS - or it doesn't have the things that makes the other tablets as good as they are. Namely, utter simplicity. This. Is. Windows.
That said, we'll apparently see a lot more in September at Microsoft's Build conference. So I'm still hoping to be blown away as we get deeper inside Windows 8.
