Indeed. I use emacs just for SLIME, and I keep running into tiny corners. I've got a .emacs that rounds some of the corners off, but it's still not perfect.
Which reminds me, if anyone knows how to get backspace to close the minibuffer when it's empty like vim does, I can smooth the most annoying corner I run into right now...
Gneve is actually quite a powerful video editor. A lot faster than click-click-click for power users.
Also with emacs' command recording facilities, it's far easier to reproduce your editing actions and keep them as scripts so that others can see what you did to go from a raw file to another intermediate file.
Well, emacs is scriptable in a Turing-complete language, so it can do anything any other computer program can do. Of course, that doesn't mean it's feasible or even preferable for it to do any of those things.
