I do most of my editing in emacs. I tried fairly hard to learn vi back in the late 1990s (even buying the O'Relly book for help), but I cannot get the habit of separate command and writing modes; I very frequently forget about modes altogether, and even when I don't I forget which mode I'm in until I try to type something. I usually have several emacs sessions suspended and ready for me to work on with an fg command, but I have also written a script that lets me easily use cat to append to or create a new text file from the command line, when I just want to add a little without waiting for a new emacs session to load.
