I repeated vimtutor for a few days in a row trying to following this nice Vim learning plan [1] I saw on HN and I gave up trying to switch to Vim as my main text editor after that. Even though I knew how to perform most of the basic operations, the fact I had to switch to normal mode to do anything more complex than editing of the current line felt just too unusual to me. I mean, I'm comfortable editing files on remote servers in Vim now but I don't think I'd ever be considerably more productive in Vim than in IntelliJ/Sublime.
