I'm going away for college and am looking into purchasing a new laptop. I'm currently using an almost 3-year-old 15" MBP. I like the idea of the portability of the Air, but the Retina is so appealing. I'll be a Communications major, so heavy-duty work processing isn't necessarily a priority. I was also considering the 11" MBA but figured that would be too drastic a change from the 15" screen that I'm used to. Please advise!
