That's why I'm so glad I bought a Mac when it was time to buy my laptop. I went off to college right when Vista came out, and a lot of my friends bought PCs with Vista and had so many problems with their school work. The computers on campus run on XP and anything my friends did on Vista couldn't be opened on campus. I never had that problem, even using a Mac.
Not to mention their computers ran ridiculously slow, even if they only had one program open. I'd go crazy.
