I don't have any RSI issues but I love the idea of alternative/improved keyboards and layouts and have accidentally become kind of an aficionado/collector. I have on permanent rotation and have written reviews of a Kinesis Ergo [0], Truly Ergonomic (TEK) [1], TypeMatrix [2], and Happy Hacker [3] and I'm looking seriously at buying an Ergodox one of these days. I happen to like and dislike each of those keyboards: each has advantages and disadvantages. Same goes for Dvorak (which I use regularly) and Colemak, etc. I'm hard pressed to say which is my favorite, but I like each for different reasons and conclude it would be impossible to combine them into any "perfect," ultimate keyboard.<p>One thing that almost never comes up in these discussions is the need to change or rotate keyboards. I love the Kinesis but eventually get tired of it, and am happy to move to the TEK, which then starts to bother me until I move to the TypeMatrix, etc. Every keyboard and layout improves some part of typing while exacerbating another. Switching keeps you nimble. I suspect it's like bicycles, of which there are infinite variations. If one bike hurts your wrists and another hurts your legs and another bothers your neck, switch every few rides.<p>[0] <a href="http://therandymon.com/index.php?/archives/167-Typing-in-Style-with-the-Kinesis.html" rel="nofollow">http://therandymon.com/index.php?/archives/167-Typing-in-Sty...</a>
