I'm going to buy my first Mac soon. As I would like a notebook and have always wanted a Mac, but have never had the cash to get one... plus, being in school a PC was almost necessary at my college. But because I don't really NEED a laptop, and it won't be used for anything TOO intense, I'm considering buying the base MacBook. However, I want 2Gigs of RAM. I've read all about how you can use third party and it's just as good as spending the ridiculous amount apple charges... but I'm wondering... can I reuse the 512MB stick that comes in the MacBook? I have a PC that only has 512MB of RAM and I've just been putting off getting another one. Will this work?
