I really, really want to use Emacs. I like the ideas, I like the addons, I like the lispiness. What I can't get over, though, is the pinky contortions and multiple chords required to accomplish things in the editor itself.
I'm not a big fan of vimscript, and the addons seem more clunky, but being able to hit a single key, rather than a chord, or series of chords, to accomplish the basic text manipulations, makes it really hard for me to stop using vim and use emacs for more than a few days.
