As an Emacs user, I've never found Emacs-ish keybindings in other applications to be helpful. Take Textmate, for example. Its default keybindings are a little bit Emacs-ish, and they're just enough to lull me into a false sense of security. Control-[f,b,a,e] do what I expect, but as soon as I try to go forward a word (Meta f), the Find dialog box pops up and steals focus.
In applications that don't try to emulate Emacs, I get slapped on the wrist the first time I try an Emacs command; it's immediate feedback that "hey, bozo, this isn't Emacs".
