I would have to agree here. The productivity gains are remarkable when one takes the time to think a little bit before typing, or learn more keyboard shortcuts for Emacs/Vim, or be able to apprehend a holistic view of the application and problem domain. A second note: Emacs is the one piece of software that makes me the most productive.
