I'm thinking about using Windows 7 on my MBP, but I have a few questions first. When the key expires will all my data be deleted as well or do I just need to get the full version? Silly questions, but does the two-hour shutdown really mean that my computer will shutdown every tour hours? I was planning on getting Windows 7 when it came out to use programs and play games, but I heard about this RC thing today. So do you guys think I should do this at all?
