I installed Windows XP SP2 on my brand-new MacBook yesterday. The installation was a breeze (except it took REALLY LONG, for some reason) and after installing Windows has superb performance. Quite honestly I have never had such fast Windows before (even though one of my desktop computers is Athlon X2).

Very impressive. The only downsides are: there is no way to right-click on touchpad when in Windows. Which means - mouse is a must in Windows. Camera does not work either :( Which is no surprise since Bootcamp instructions do mention there is no driver, nevertheless - it is sad :(

But in any case, I can now use my MacBook for ANYTHING I need and I can hardly express how awesome that is!

Below are couple of screenshots for your entertainment:
