I bought my Air back in September 2013. I am basically using it for reading text, using Microsot Office (Word, Excell, PowerPoint), surfing the web, email, a bit of gaming, and looking at photos I take with my iPhone; that´s basically it. It does all these things well. No crashes, and apps open as soon as I click on them I love the portability; I mean I barely feel its weight when it is in my backpack. However; I see the retina display every time and again and I am starting to fall in love with it. I know it may sound stupid or ludicrous considering to buy a new laptop after just a few months of getting my Air. Nonetheless, I would like to hear other people´s opinion. Should I buy a rMBP I don´t think I would keep both. I would have to sell my Air. The rMBP 15 costs a considerable amount of money, so selling my Air would help a little.
