I'm getting a new MacBook to run Parallels and XP Pro, and wondered how much HD space I should plan on setting aside for Windows? I only have a few Windows-only applications (less than 1 GB with data). I just wonder if the 60 GB white one is big enough, or if I should spend the $200 and get an 80GB black one, or just upgrade the white one to a bigger HD? I'm currently using about 45 GB on my current PB that I'd be switching over.
