People hate doing it because it takes a long time to set up alot of programs.
And because I don't think it's necessary in most cases, especially with XP.
You should be able to clean out old drivers if there's a problem. That, and run adaware/spybot at least once a month, and reinstalls are pretty much a waste of time.
