I'm currently waiting to pick up my first Mac as soon as the MBPs are updated. I've been lurking around here for a while now, helping out where I can. As a switcher, I'm undoubtedly going to need to use some of my Windows only programs (IE, Paint.NET). I'll probably use Parallels to fire up those programs while in OSX, so I don't have to reboot. However, I also like to game, which would require the use of Boot Camp. My question is, is it possible to use the same copy of Windows for both Parallels and Boot Camp? Like if I go out to Best Buy and pick up a copy of XP Home, will it work for both Parallels and Boot Camp, or will I need two copies due to usage restrictions?
