Hi I was going to get the basic 13" Air with 4GB Ram and 128GB SSD, but then I was offered a one week old 13" Retina with 8GB Ram and 256GB SSD for only $50 more. I am mostly going to use it for running mail, text editing and having a lot of browser windows open at the same time and then I am travelling a lot working on the road so lightness and silent fans matter. Stability is also important which is why I love the Mac's. The screen doesn't make any difference to me. The Retina sounds like a great deal; strong but still light but I heard that there is a lot of issues compared to the Air. Is the Retina a better choice or should I go with the Air?
