Of course I do!
First of all, I don't use Caps Lock since I don't spend all day on Facebook.
Second of all I DO use Ctrl, since I spend all day in either Atom or Sublime Text, not to mention iTerm and PuTTy (depending on platform).
Third of all, my finger doesn't bend that way, so if I want to use the far left bottom key I have to move my hand, which takes time, effort, and leads to RSI according to people who know about those things.
