Coming from a 13" late 2008 C2D Alu unibody, I just got the 15" with nvidia this week. It's huge and it's a biest.
I think 13" is the ideal size for usability and mobility. But I need power for heavy editing in Aperture, so a 13" is no option.
On the other hand, the new 15" rMBP has the exact same weight as my old 13" (2.02 kg) and fits in the same bag.
A showstopper for the big one would be if I was constantly on a plane or train or in meetings all the time. That can get really inconvenient as even 13" is pretty big in such situations.
