For me, it is feeling like part of my OS. I have to use a whole bunch of other Mac apps, and Emacs (or vim) don't fit in. Mouse cut+paste is dodgy, and they use a whole bunch of different shortcut keys (I just instinctively type apple+s for save, apple+f for find, etc). There seems (based on other users I know) two sweet points -- put your whole life in emacs, and give the other apps you have to use Emacs shortcuts, or no Emacs. Some people's brains might find it easier to switch between two sets of shortcuts when switching between apps of course.
