hey guys just actually wondering if anyone to could tell me something that the apple.com website doesnt about the differences between teh two MBP. i currently have an 2.33 MBP i purchased about spring 07. Im looking to purchase and new MBP, preferably when snow leopard come out, after combing through the refurb section i noticed a 2.4 uni. then tried to compare it to the 2.53 model and im still at a cross road. any info would be great.
