Using Emacs and/or Vim is also a test of how much you care, primarily because they're not the default anymore, so anyone who uses them cares enough about their programming environment to use a non-default editor, and one which has a rather higher barrier to entry than most at that.
(Although, to be honest, using the GUI version of GNU Emacs as a Notepad replacement is possible: Just ignore the keyboard commands and interact solely via the menu up top. You even get access to at least some neat major modes this way.
Still, Emacs isn't the default, so anyone using Emacs probably knows why, and won't be the kind of person to use it without getting more out of it.)
