Afaik, if you have Windows XP, there isn't really much of a reason to upgrade to Windows Seven. Compared to Vista, it's probably an improvement, however.
I like some of the UI improvements.
It's still not a patch on what you can do using X and many window managers, but it's an improvement on the disaster that is the classic Windows UI.
Mostly it's simple stuff like being able to navigate alt-tab with the cursor keys, having thumbnails of windows in alt-tab and being able to rearrange the order of tasks on the taskbar. I didn't have a problem with Vista on my laptop hardware and 7 just runs smoother than that. Will be trying the RC on my old Athlon XP though, just to see how it runs.
Still has all the classic Windows problems though, like regular BSODs, generally shitty GUI and too much bottom wiping, but it wouldn't be Windows without these problems, since they're common all the way from 3.11 to now.
