I have recently received a first gen MacBook Pro, a 2.16GHz Core Duo model. It is a basic model, no upgrades, but was free. What sort of things can I do with it, Snow Leopard, a version of Windows 7? Also, what sort of things can I upgrade, aside from the HD and RAM, I've heard that you can upgrade the AirPort Extreme with an n-based card, any success with that? Sorry to sound a bit noobish with something like this, but I'm not exactly sure what I can upgrade in a computer like this. I will be replacing my PB G4 with this, as a netbook replacement. I would like to use what capabilities it has, instead of just passing it on to someone else. Also, it has zero scratches, and it is actually a sealed computer, never used, because the previous owner "didn't want to learn something confusing like a computer".
