I'll wait for Windows Sile.
Pros: Some interesting features they took from OSX with file management and menus.
Cons: Microsoft should fire their programmers. I beta tested for the last 8 months in hope the final would fix the whole structure, but it didn't. Every background process (and there are about 3x as many as XP) uses as much ram and cpu as possible. It's like they came up with all these new looks and ideas and tossed them together and didn't bother to test the integrity of it all. The Areo effect is lame (look at XGL in comparison). And 64bit version is useless for now.
Other Thoughts: Boot time with E6600.. almost 2 mins. with XP, 12 seconds. with linux, 8 seconds. I say maybe wait for Service Pack 2 or 3 to bother.
XP is fine for me.
