I have a Macbook Unibody 2.4 and an iMac Aluminum 2.8 C2E. I just wanted to play around with Windows 7, not cause any serious issues, and just, you know, try it out; not do any serious testing. For my purposes, do you think Im better off downloaded the 64-bit of 32-bit version? And which computer will handle windows 7 better? Thanks for all your help. Oh, and I'd do my trying out/testing in VMware 2.0, not Bootcamp. Is this a bad idea?
