Well, I can explain how I use it. I have my Sublime in legacy mode, which enables some vim like controls. And I benefit from Sublimes super fast text rendering, it's nice fonts and colors, the way it integrates with my desktop environment, how fast it interacts with plugins that spawn popups and analyze my code.

And then every once in a while I need to do some cool text transformation, and it doesn't work, so I launch a terminal, edit the file in Vim and work my magic. Then I exit Vim and continue in Sublime. Ideal? No.. but it's the usability of Sublime with the features of Vim.. every once in a while..
