'The main argument for sticking with VIM is the good design of key-commands which is deeply embedded in "muscle memory".'
I use vim because i learned how to touch type, and vim commands are configured around the home keys for touch typists. Throwing out labels like "far too VIM centric" and "learning emacs spared me the time" implies that vim is the problem and Emacs is the solution. Maybe Emacs works for you and many others, but it doesn't work for "the rest of us." Just be happy that you can use your tool. I know i am happy that i have mastered mine. I tried Emacs several times and i have never enjoyed using it. I am also happy we live in a world of choices. Don't assume that my choice is not an informed one.
