A good question that I was going to address, although I am a long time Emacs user so my experiences are different. A similar question on a much simpler key mapping task is what do you do about cut/copy/paste? I found that if I had learned the key bindings when I learned to touch type, they were easily translated to another keyboard. Once I disconnected where my fingers were going with what action I was trying to perform, it didn't matter if the keys were in "logical" spots on the keyboard layout-wise. That being said, vi style keybindings probably don't transfer very well from a comfortability or convenience standpoint. I know that navigation in elm and Gmail is always awkward for me on the Dvorak keyboard. The Dvorak keyboard can also totally confuse some FPS type games that rely on W, A, S, D for movement.
