I have tried parallels since the idea of seamlessly switching between operating systems is appealing, and I do not have a copy of Windows XP with service pack 2 on it already. The installation of Parallels has been a pain in the ass. The devices do not show up, including USB and disk drives, so I have never got to the point of installing windows xp. I think I will try bootcamp and try to get a friend who has the latest windows xp with service pack 2 on it. Larry
