I like xp my wife has vista had to use computer a few times when mine was being fixed give me xp anyday.
My humble opinion is that Win XP is the best OS. Ever. I'll be using it until M$ stops supporting it. Then I'll probably continue to use it for ever. My 5 year old Celeron 2.2 Ghz can't handle much else, least of all Vista.
Windows XP and Debian linux And the day windows XP starts getting buggy due to a lack of support, Microsoft will be gone from my computer entirely
