I'm trying to decide if spending about an extra $250 is worth getting a 2.8 MBP model. I'm going to be using my MBP for pretty basic things like surfing the net, putting pictures I take with my digital camera on there, itunes, and ichat. Logic Studio will probably be the only really large program I plan on using. I also plan on buying Snow Leopard when it comes out. I hope to get a good 4 years out of this computer so I don't mind spending the extra cash if it will make a difference in the long run. Should I go with the 2.8 or the 2.53? Thanks
