2 questions, actually. On this amazon page http://www.amazon.com/gp/product/B000QW6QJG/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1 it says the model number for this Mac is MB063B/B. I looked all over Apple's site, and I couldn't find a Mac with that number. I did, however, find this: http://support.apple.com/kb/sp18 and it matched everything on the amazon page: except the model #. This leads me to believe amazon has just made a mistake and the model number for the macbook is actually MB063LL/A. So two questions: 1. Is the computer on the amazon page a MB063LL/A or a MB063B/B? 2. Is it possible for the computer to take more than 2 GB of RAM? I've heard of it reading 3.3GB tops but I'm not sure. Thank!
