Pulling the trigger on a MBP this weekend. Basically set on getting the 15 with nVidia. Do those that currently own 15'' rMBPs wish they had gone with the 13 because of portability etc? I work in film and photo, and go between a 27 inch iMac and 11 inch air. I need something powerful and portable that fits nicely between the two. Afraid 13'' will piss me off when it comes to going through my library of photos etc, and i'm worried that 15'' will be bothersome to lug around because of how heavy it is etc. For those that currently own the 15, what do you use the computer for, do you wish it was smaller? Buyers remorse? Love it all around? Thank you! ------------ Lots of very helpful experiences and anecdotes here. Thank you all. Confirmed I'll be going with the 15.
