Hi, I have the chance to get an older unibody aluminum macbook pro for $650. I haven't had one in a while so I'm not sure if this is a good value or not. I'm hoping you can give me some advice. It's for the 13 inch model 2.26ghz, stock - 2gb memory, 160gb, etc. It hasn't been used much at all - some light scratches, but nothing major. The battery has less than 20 cycles on it. It's just for the macbook pro and the charger. I know the person who is selling it, but he lost/got rid of the box etc. as he moved, but he's honest. Unfortunately the warranty has expired. Do you think this is a decent deal, or do you think that the newer models are worth the extra cost? Thanks!
