Hi guys So I have had a rMBP, pretty much since launch. I recently however whilst browsing got a very good deal on ebay for a 2012 (latest model) 11" MBA. I told myself that I would see if I liked the MBA enough and then if so, sell the rMBP (the extra cash would be welcome, I am not desperate for it though). If not, I would re-sell for profit the 11" MBA. Anyway I have been using the MBA today and really the retina screen has spoiled me. There is such a difference between a retina and none-retina screen - I do fear the experience between the two is so different that you cannot return to a non-retina display, having used a retina laptop for an extended period of time. Has anyone else had this experience yet? For what its worth I find the 11" screen fine, size wise - which was another concern I had. I do not really need the power of a pro machine either. The only real hesitation I have with keeping the MBA (and selling the rMBP) would purely be the screen, which again (for me) provides simply a different experience. My perfect mac would undoubtedly be a retina Macbook Air, which I understand from the chat on these forums is not a likely release in 2013. Is the retina screen alone enough to justify the cost of the rMBP, particular in my scenario when I guess I have a clear choice between it and a much cheaper 2012 non-retina Air? Just interested in your thoughts/experiences retina MBP users..
