hi, I'm thinking of selling my MBP 2,16ghz C2Duo with 4gb ram and 120HD. In order for me to buy 2 Macbooks. i would buy one MB 2.2ghz SR and the oher one would be (for my girlfriend) either the 2.0ghz santa rosa or a normal C2Duo model. what do you guys think? is it worth selling my MBP for 2 Macbooks? thanks.
