Hello, I'd like to start by saying that, I'm not that fluent in English, so bare with me. I have a dilemma, because both choices are good things to consider having. Mainly MBA and rMBP. The thing is I'm mostly going to do drawing/business stuff on the notebook. Using Photoshop, Illustrator, Lightroom, and of course some drawing programs, like Black Ink for example. Not to forget as I'm still a student, I will be using Office or maybe try to use iWork. And also quite gamer at heart, but not that much haha) Could use a game like mmorpg or moba. Do I need 8 GB of RAM or 4 Gb will suit me? That retina display really catches my eye for drawing purposes or will MBA do just fine? Battery life is fine, I guess. So that's not much of a deal. Oh right. Both have 13 inch. I'm quite at a loss, as I never used Macs before. So please help me with that choice. Any help would be greatly appreciated.
