I've been looking to replace my 15" PowerBook G4 for some time now, and really stretched my patience for this update. Going to grad school next year, I wanted something portable, and hoped to buy the 13" the second they gave the line a performance boost. Unfortunately, they skipped over it, and I decided to go with the 15" for the i5. Sure, the Core 2 Duo would have been sufficient for most of my needs, but I play in Photoshop/Logic Pro quite a bit, and knowing that apps like these and more will soon be optimized to take advantage of the threading capabilities, I felt going with the 13" would put me at a long term disadvantage. I guess I sacrificed the portability for what is, to me, a better long term investment. The bigger screen isn't so bad either, although, the new 15"s tend to have a bit more fat around the edges than their PowerBook predecessors.
