People forget that Unix itself is one big IDE. I use emacs to edit code, but in another terminal window I use make to compile or run tests, "find" and grep to look for stuff, tail to look at logs, custom shell scripts for lots of other things, etc etc. So emacs isn't an IDE, it is just a text editor, and the best one I know at that (I love vi for quick configuration tweaks, but not real coding).
