The complexities of Vim are rather exaggerated IMHO - it's mostly an exercise in keyboard shortcut memorization. It was used principally in all my CS classes back in university, and everyone seemed to acclimate to it pretty quickly.

On the off-chance that you somehow encounter a real world situation where you have to log into a POSIX machine that has no other editors (nano, etc.), you can just learn it then.

I mean you're not defusing a bomb - it's not like you couldn't pull up the shortcut list on your phone and get acquainted with the majority of what you need in a few minutes.
