Here's the deal: I'm thinking to replace my old Qosmio (2008) and I want to enter in the OSX ecosystem. So I have 2 options in mind: -13" rMBP 2.6/16/512 -15" rMBP 2.0/8/256 I know that only me can answer this question, due to my needs, but I would like to read your advices. I can get both macbooks for the same price, so I'm asking your feedback. The 13" option is more portable, bigger ssd and 16gb ram, seems a killer combination here; On the other hand, the 15" option has quad core processor, bigger screen, better speakers... Since I'll be using it for some web browser, watching series, music editing, college presentations and I need to carry it around everyday, what are your thoughts? Which option seems to you the "go for it"?
