I have a MacBook air 13", the basic one with 4GB of ram and a small SSD. It works fine. I can't really see why it would need to get a whole lot better honestly. If I need a "big" computer then I use my desktop, and if I just want to read then I use my tablet or my phone. I would buy another apple laptop sure but not because of the specs really. They are just good computers in a world where there are lots and lots of good computers. I think apple is right to just keep on keeping on with these machines anyway because there isn't much innovation in terms of parts happening now. Touchscreens are a gimmick to me and newer cpus are only a little better and not worth the price of the upgrade. New computer specs are basically about as exciting as reading about innovations in Refrigerators or other durable goods.
