I haven't used a Mac in like, 10 years, mostly because my parents never bought one and there weren't any in my school. So now I'm thinking of buying a Mac laptop. I don't want to, nor can I invest more than about $500 in a laptop. I've been surfing Ebay, but don't know what kind of old school laptop to buy. Any suggestions? Someone told me the Mac Book was a good beginners computer.
