You may be kidding, but you are right on both counts. Emacs is so much better when your control key is next to 'a'. Your hands prefer it when 'aoeu' is right under your left hand. You will prefer it when your colleagues can't figure out how to type on you computer.

I was serious in that Ctrl-Z is easier to hit with dvorak, and with caps lock as control it becomes even easier, but I don't expect anyone to switch for that reason.
