I have a 2016 15" rMBR. I'm considering selling it and getting a 13" with an i7 processor and 16 GB of RAM. I'm not sure if I'll regret this decision. I do film editing on Premiere and FCPX. Not a ton and not with tons of effects or motion graphics, but enough that I'm concerned about losing the quad core processor and the graphics card, as well as the larger display. But the 15" is cumbersome to carry around. I did sell my last 15" for a 13" and did miss the screen size, but I figure I could always buy an external display. So mainly I'm just worried about losing the processing power. Opinions? As long as FCPX and Premiere will run relatively well on the 13", I'll be fine.
