I was in the same boat. First real gig out of college (well besides the stints during college) and I saw how fast my boss flew on his keyboard while editing files in vi/vim. Here I was painfully editing config files in nano while he was flying by with vim.

I took the time to learn it and have been using it since. I now try to pass the torch by showing folks on my team the neat things vi/vim can do. People are amazed how much you can do it with just few short keystrokes.
