I've been thinking about switching to Colemak but the fact that I use Vim daily has kept me from seriously considering it.

While I certainly can remap some keys in Vim, I'm not sure if that's such a good idea in the long run. Some keys, such as h,j,k and l are no-brainers - those should be remapped. But what about w, b and e? When I'm using those keys it's all muscle memory, but should I really change w to y (word to yank)?

Do I want to spend my time learning a new keyboard layout AND relearning how to use Vim? Ultimately I've decided that Qwerty is good enough for me. I don't have RSI and I can type at a max speed of over 90 wpm (I probably average in the 70s for "real world" typing).
