I wanted to get some feedback or just opinions. I have a 27 inch i3 IMAC, that I am going to trade for a i7 15 inch macbook pro with a matt screen. Both are current 2010 models and about the same age. I am also giving the macbook owner 500. Do you think this is a good deal, or a deal worth doing (from a money stand point only.) And what should I look for before the trade ? Thanks for your help!
