Plus it's significantly slower. And don't anyone say the upcoming SP1 ‘fixes’ it.

P.S. Oh, yeah, forgot - it doesn't bring a single bloody positive feature over XP. In fact, design-wise, it's pretty well mangled many of the things that were good about XP. So you have to ask yourself - do I want the newer product, which is slower, has reports of more driver issues, and has a design philosophy that's bonkers, or stick with something that works?
