Hi all. Have a white Macbook (2Ghz, with 2GB RAM) I bought it in May, and it is heavily used in night time music venue environments (often very very sweaty). I also have fairly sweaty palms Consequently, there is really bad staining on the palm rests. It's gonna be totally messed up in 6 months time I think. My local apple store said they'd replace the palm rest casing for free up until my warrantly runs out. But, I really would like to swop it for a black Macbook with the equiv config now. If I could find someone up for it, could i just swop the hard drives, and that'd be it????
