I'm just as torn as you are. I originally planned to get a base 15 rmbp and use my old 2010 macbook pro 13 to supplement it. But then I figured get more ram. Then I figured that I should get more SSD space as well. Then that put it about $120 off the price of rmbp with dGPU.
Now I'm thinking maxed iMac 21 or 3TB fusion on a 27 iMac... As I can save a little. But damnnn that screen looks nice on the 15 retina. It never ends.
I'll be doing my thesis on the new machine this year and I have some pretty heavy (and bloody expensive) software for textual analysis of 3 languages. So my 13 + a 21 or 27 could work. Portability + processing power....
The decision process never ends....
