I admit I have recently moved, on my Mac, from BBEdit to Emacs for most things, although Emacs has also taken over from Ulysses and Day One for me. But there are still some things that I end up doing in BBEdit, because it's kind of a multitool for text manipulation that, unlike Emacs, exposes its power very easily. As much as I'm growing to love Emacs, there's something to be said for an editor that doesn't answer so many questions with "write a little Lisp".
