Ok, I am a life long PC user who has tentatively decided to make the leap to Mac, but right now I just can't really afford even a EDU discounted Macbook, so I started looking around on Craigslist. Found the following and was hoping that somebody who knows more than I do, could give me a hand. I don't really need the computer to do that much other than e-mail, web surfing and itunes. Here are the specs: Apple Macbook (Black) 2ghz Intel Core-Duo Processor, 512MB RAM, 80GB Hard Drive, and OS X Tiger 10.4. Applecare till 5/20/2009. I think hes asking around $700 for it, which seems decent, but I don't know if i'll end up spending more upgrading the RAM (if I need to) or upgrading to Leopard. Please let me know what you think, thanks, and thanks to everyone posting on here, i've been trolling around for a while and it seems like a great place for advice.
