Does anybody know how much of a difference there would be between a 2.5 and 2.6Ghz MBP? It's not really worth the couple hundred dollar price difference is it? Also, what about the 7200RPM harddrive, do you guys think that's worth it? Does anybody know what model harddrive they will be using and whether it eats up battery time or whether there is a noticeable speed difference? Thanks for your help. I'm kind of underwhelmed at the update after waiting for a month and a half but hey.
