Editor

This board needs some threads. I'll start the mandatory editor flame thread that all programming discussions require.

Emacs r0x0rz. Vi sux0rz. Vi users eat aborted babies for breakfast.

Actually I use TECO, but that's beside the point.

Windows: Notepad++
Linux: Gedit.
CLI: nano

I tried Bluefish, but if felt buggy and I'm pretty sure the syntax highlighting was broken. (Also possibly the code folding).

Vi is balls.  Vim is serviceable in a pinch, but I don't prefer it for long projects.
