I have a white macbook I bought in July. 2.4, 250, 4 gigs of RAM. Question. Is it possible to buy a new aluminum macbook, swap out its hard drive with my current HD, pop in the extra 2 gigs of RAM, and have a working aluminum macbook with all my current files and whatnot? Or is there an OS issue with the trackpad? I'm thinking of maybe doing that and then selling my current one with the new HD in it. Is that easy enough to do?
