I don't need a ton more "innovation" (touchscreen on a laptop is a gimmick IMHO) in my macbook and it's plenty fast for what I do (run 2 external + laptop screen, 1-2 IDEs, chat, email, chrome, firefox, sequel pro, etc) but I think I'll go to the 15" next for the real graphics card and the ability to run 3 external monitors. All that said it pains me that Apple has not made any real improvements in quite some time. I was thinking about this the other day, I normally update every 2 years and I passed that mark 4 months ago but I really don't feel like I'm being held back in any way... Also they cap the RAM to 16GB (which I have) and since I can't add/replace it I don't really want to buy again unless the RAM can go up to 24/32.
