Hi all - I'm new here. Sorry if this has been asked before.. Unfortunately where I live there's nowhere I can go to look at the retina MBPs (unless I drive a half hour or so)... So, a couple of questions - What's the 15" rMPB like in terms of portability? Do those of you who have one wish it was smaller/lighter? I'd definitely prefer the 13" size, but lack of dedicated graphics/quad core is making it a tough decision... Is the 13" rMPB powerful enough for casual video editing on the road? I do most of my work on my desktop, but it would be nice to have a laptop that can handle it when I'm away on projects. I use Avid Media Composer, and I wouldn't call it the lightest of applications.. Any info that could help me make a decision would be appreciate!
