If Windows Vista was Microsoft’s folly - a mish-mash of ideas not fully baked and aimed at multiple constituencies - Windows 8 is Microsoft’s rebirth. To get ecstatic about it isn’t quite the direction I’d like to take this mini-review, but let’s just say that Microsoft is on the cusp of getting things right. As we said before, Windows 8 will ruffle a lot of feathers. The first and most obvious comparison is with the new Windows Phone interface. The “Start” menu is gone, replaced by what amounts to the entire Metro UI. This UI - the one with the multiple, animated squares, is the one that matters.
