Im trying to decide whether I should buy the new Macbook or the old Macbook Pro. Since the new Pro came out, the previous version can be bought new in the range of $1400 and $1500. Im not concerned with the different casing or the multi-touch trackpad that the Macbook offers, but do prefer a 15 to a 13 screen. Given that the prices are very similar, is there any reason to buy the new Macbook over the old Macbook Pro? From a performance standpoint, which notebook is better? Thanks for the feedback!
