I can get my hands on a new sealed MBP 13" 2.56ghz, but it is the 'old' one. I can get it for 2/3rd of the price of a new MBP 13" 2.4ghz. They both have 4GB of memory, but the old 2.56ghz model has 320GB hard disk (versus 250GB). So the older 2.56ghz is faster than the newer 2.4ghz, right ? Or does it have less cache or something else that i'm missing ? I know the newer ones have a better graphics chip but I really don't mind that. So guys, any thoughts/advice is welcome .
