I haven't seen any particular advantage to Windows 7, and it's a lot slower than XP. I wish I had a hundred XP installation CDs, since it now seems to be impossible to find in stores. As every system administrator knows, never, ever "upgrade" something that isn't broken.
Whilst reasonably accurate, that's a bit of a broad brushstroke there Anthony. I'd refine it slightly by pointing out that the entire network stack has been rewritten for Vista and 7, and in certain circumstances this provides VERY big performance advantages.
