You might want to consider upgrading to Windows 7 eventually. I can understand why a lot of people didn't go to Vista (because it was garbage), but Windows 7 is definitely an upgrade of XP. I probably won't be upgrading to Windows 8 though, as it looks terrible, and I've heard the same.
Windows 7 is the XP of this generation. It won't be losing support any time soon, either.
