Steve Wozniak, Apple's co-founder, doesn't seem to like the companies new Boot Camp software which enables Mac users to install Windows XP on their systems. It's not that he doesn't like Windows, it's because it requires you to reboot:
In an interview with the Seattle Times, Wozniak indicated that he does use Windows but not a PC. Instead, he currently uses Virtual PC to run Windows so that he can switch instantly between the two operating systems.
Like many users, Wozniak does not like to have to reboot his Mac in order to use a different OS. Wozniak also mentioned in the interview that he doesn't believe Boot Camp will make PC users jump up and make the switch to a Mac. "What I really want is just a window that I can go back and forth instantly. I don't have to reboot. I go to Macintosh, I go to the PC, I go to Macintosh" said Wozniak.
