I tried to guide a friend through changing his video resolution. He didn't know he had vista, and neither did I. the general conversation was "I have no tabs! what the *censored* are you talking about?" and I was just going what the heck? then I realized, Vista makes everything easier by requiring ten times as many mouse clicks to do anything.
In retrospect I highly doubt many options were changed from defaults... XP is annoying without reconfiguring almost everything.
