I know someone locally that is selling a macbook 2.2 Ghz processor, Intel Core 2 Duo, 2 Gb memory, 160 Gb HD, airport extreme card, leopard 10.5 for $400. is that a good deal? i dont know what year it was made and which mb or any other specs on it, but if its in working condition do you think it is worth it? it is for my girlfriend who needs a mac that she can run the adobe suite on, would this machine be capable? thanks
