New to Mac. Never owned one and never used one actually. Make a long story short I planned on buying a brand new macbook. But looked on craigslist and i've been negotioting with this guy who has a black macbook, Intel core duo, 2GB Ram, 180GB, superdrive he says its a late 07 model. Pictures he attached looks mint, spoke to him on the phone and talked him down to $600. young kid who is a DJ says he bought if for that purpose but doesn't like it and is going back to windows and will take the $600. I'm going to get it from him tonight. Knowing the model and specs is this a good deal or should I pass. My gut is telling run don't walk. All of you being experts I could really use your advice.
