Hardly anybody would want to learn all of the features ofcourse. There are advantages of using vim which other editors can't compete with (imho):
- A just booted VM with with no window manager installed. You have very few choices, but can always count on vi being there.
- Abstraction: One builds up the knowledge of different things over a period of time. For exaxmple, once you learn 'w' is next word, it can be combined with the new knowledge of 'd' for delete quite intuitively. Not saying other editors don't have that.
- Each popular editor I know of has a VI mode built in (or easily available). So, being comfortable with vi means being able to use any of the mainstream editors with vi mode, but not the other way around.
