I know this issue has been debated and I've read the threads. Here's my situation: my teenage daughter wants a MacBook (likes the 'looks' of the white vs. aluminum). As for me, I like the MBP for all the obvious reasons, memory, SD slot, etc. The major issue I have with the MacBook is that it does get extremely dirty, and yes, I've seen that you can use the Magic Eraser but who knows if it may/may not damage the white casing. A weird thing I noticed in owning a previous generation MacBook is that colors from sheets, etc. seem to build up on the casing, removal is difficult at best. I know we're not supposed to use these in bed BUT remember this is a teenager and she knows EVERYTHING. Anyway, what's your thoughts, would you stand firm on the MBP, any issues you've had in keeping the MB clean? Thanks.
