hello, im thinking about selling my 13" Macbook that has 4GB of RAM and a 320GB Hard Drive. I bought this one in January, before the new ones came out, and i wanted to know whether i should sell it or not. It came with 1Gb of RAM and a weak 80GB HD. I really upgraded this baby. Im wanting a MacBook Pro, and im hearing the new ones might be coming out in October. I want to sell it before the price on these macbooks drop... any tips from anybody?
