Should I sell my retina MBP15 and get a ipad mini + homemade desktop. And then later down the road sell the ipad mini for an improved ipad mini with retina. Or should I just keep it, buy the ipad mini and a 27" external monitor. I really regret my decision. I basically have 2.2k machine that I use for browsing the web, music, movies and facebook. Just because I wanted a retina display, 15" and because it was thin and light. But I was wrong about the later cause its still not mobile enough. Very rarely do I do heavy work and I am not a gamer either.
