I always found modal editing most valuable when editing and navigating through large bodies of text. I'm not quite sure that it makes sense on the command line, where you're rarely dealing with more than a few lines of text, and seldom need to rearrange those particular lines. Nevertheless, I switched to zsh on Sunday, and with it, vi keybindings. It's getting better, but it still doesn't feel quite right.
