Three weeks ago I swapped capslock and Ctrl on all my usual systems, much to the chagrin of Daniel when he foolishly tried to use my keyboard. I'm now quite happy with the positioning of Ctrl - it was surprisingly easy to get used to.
It is not a coincidence that this is Tip #1 on various lists of ways to use emacs more effectively. I find myself wanting to ditch vim… perhaps this is just asking for a holy war.
My reasons are quite vague at the moment, but have something to do with wanting consistency of user interfaces across editor, shell and, er, IRC client. One other thing I've noticed is that very few people seem to write many vim macros - I suspect that having lisp to work with will actually make this easier. Also, of course, it's a GNU project! As part of that, the licensing is vastly more sensible than vim's.
So, seeing as forcing myself to use the capslock key as ctrl seemed to work, I suppose I'd better force myself to use emacs regularly instead of vim, and see how it goes. This involves purging vim from machines where I can, and aliasing 'vim' to 'emacs' in places I can't. Perhaps this will scare more people away from borrowing my keyboard.
