It's interesting that none of all this is really the reason why I use what I use ... I use vim simply because it is ubiquitously installed on every linux and Mac system no matter what or where, including keybindings in every other editor or IDE I would ever encounter, including the bash command line (after set -o vi) and FireFox (with SurfingKeys).

The fact that it happens to be powerful enough to do everything I want is of course necessary, but there are dozens of editors that satisfy that requirement. Simply not having to switch out of Vim navigation or move my hands off the keyboard for the whole day across the dozens of different tools that I use is what makes it a winner.
