I am going to upgrade to 2gb in my MBP and want to use the 512 in my girlfriends Macbook. Will this be a problem? Do I need to do anything to ensure a smooth transition?
I got these crucial sticks from Newegg. Infact, I got 3 pairs for 3 macbooks and all work perfectly. I'd do the same for a macbook pro if I were so inclined (already have 2Gigs, so..). The required specs are the same, so your old memory should work in hers, and the memory that I mentioned above should work for you. Enjoy, whichever which way you go.
No doubt whatsoever: you are absolutely correct. MacBook RAM is completely interchangeable with MBP---and iMac, for that matter. I've done this many, many times.
Edit: Sorry, Eraserhead---didn't read your post carefully enough. In any event, for the OP: without a doubt, MB<-->MBP RAM swap is fine.
Except that the GF's MacBook probably shipped with 1 Gb RAM -- 2 x 512 Mb SODIMMs -- so in that case an extra 512 MB SODIMM will be useless as ... well, useless as a useless thing.
