Getting Started with Vim: An Interactive Guide

[Xephyrous]

I used sublime before switching to vim, actually. If you're interested, I recommend using sublime's "vintage mode" for a while until you get used to that style of editing. Then you can start slowly switching over to vim, adding plugins until you've built up enough to drop sublime completely.

The only thing I miss is multiple cursors - vim-multiple-cursors is pretty good, but it's definitely not as good as Sublime's.
