My reasons for being a vim user a lot more practical than those I see on these "top 10 reasons for trying X":

- In the long run, it's faster to learn and use an "efficiency" editor, so I need to learn one of vim, emacs, notepad++, etc. The differences between these are probably negligible for a proficient user.

- Of these, only vim will be installed (or vi, which has a big enough overlap that it won't matter to me) on every system I'm going to need to use.

These are, incidentally, the same reasons I use QWERTY instead of Dvorak.
