Apple added a built-in option to map the caps lock key to escape. This not only makes sense from a RSI and efficiency perspective but is also closer to the keyboard that vi was originally designed for (the escape key was where modern PC keyboards put the tab). A lot of dedicated vimers will use ctrl-[ instead of escape to avoid the inanity of reaching up there regardless of their keyboard, which is also a good approach if you're in the camp that maps caps lock to ctrl. http://vim.wikia.com/wiki/Avoid_the_escape_key http://vim.wikia.com/wiki/Avoid_the_escape_key
