I am set to buy my first Macbook Pro in 2.5 years. I had pretty much settled on the top-of-the-line 2.8GHZ model (although you can custom to 3) with the better video card. Not sure if this is overkill for someone not into gaming, but I figured the extra video memory couldn't hurt with video and picture editing. ....then I saw that the 17" is going for $200 more and is loaded with the same features as the 15" (2.8, better graphic card and memory). Anyone have any thoughts of why it may be better going with the 17"? Is screen resolution any better? I used to have a 17" PC years ago. It was heavy and a bitch to use on an airplane. However, in these past few years the 17" models have become lighter and I would imagine in Apple's case, more streamlined. Just thought I would ask for any arguments for or against the 17" Thanks!
