As I have said before, there is only one editor and it's emacs I've tried to shake the Emacs addiction but I can't. It's scary to think I've used Emacs for 15 years and vi for over 20!
From Emacs OS Xplosion.:
OS X has been with us for a few years now, and Emacs has been coming along slowly and surely. We must have hit some sort of a tipping point, and there are a whole lot of people working on the problem; the result is that life is getting better and better for the Emacs tribe. This piece opens with a brief sermon on why, if you%u2019re not already using Emacs, you might want to check it out; and then surveys the state of play and the multiple interesting emacses that are out there.
