Well, the obvious one is to move back to upgradable hardware. Why they feel the need to keep reinventing M.2 I don't know. Even for non power-users, an extra year or two out of your machine, or the remote chance to get your data back if e.g. logic board dies is definitely handy. A few other reasonably obvious things I can think of are the ability to run iOS apps in OS X, potentially even move an iOS app to OS X (there would be a hardware component involved here I would assume), pen input on the display or trackpad, quad core CPUs in the 13" model.
