I'm on the very brink of buying a Mac Pro to replace both my Powerbook and an ageing, neglected Windows 2000 PC. As a web developer, the idea is to have Win2K running IE6 in one Parallels window on the Mac Pro, and to have XP running IE7 in another Parallels window, while doing the coding in Textmate. Obviously, I need to wait until the Parallels bug on the Mac Pro is fixed, but my question is regarding the edition of XP I would need to buy. Since the Mac Pro is a 64-bit machine, would it make sense to buy the 64-bit version of XP Pro? Or wouldn't that make a jot of difference in the Parallels environment? Could it actually be a problem? Is it even necessary to buy XP Pro? Would XP Home do? Hope this isn't too off-topic a question for a first post! Cheers, Andrew.
