You guys can go ahead and laugh all you want about Windows, but let me tell you something: Microsoft may look like a big dumb ogre, but they're not complete idiots. They know that Vista is a bust. They know they are losing users to Apple and they know that if they don't do anything about it, they're going to suffer, big time.
Windows 7 is Microsoft's way of turning over a new leaf. They've already written a new, super small (40MB in-use), non-cluttered Kernel (called MinWin), and from there will rebuild windows in the way Vista was meant to be rebuilt. Windows 7 will be lean and it will be fast. It will, for the first time, be a worthy competitor to Mac OS X, and it will get done on time (or heads WILL roll......... Balmer).
Microsoft has the manpower to do it too. They just need the organization that they've never had before. The main reason for delayed OSes is bad management and legacy support. If Microsoft follows this path (and I think they've resolved their managment issues), they will once again become a force to be reckoned with.
This last decade has been an "easy" one for Apple. Windows has been the sleeping giant. But now it's awake and it is MAD. It's no longer going to be a walk in the park for Apple. This excites me, too, because it'll bring greater competition, and henceforth greater innovation between the two companies. It's a great time to be not only a Mac user, but a Windows user as well. Their side of things are about to get considerably better, I feel.
