I can recommend the Kinesis Advantage keyboard for RSI: http://www.amazon.com/Kinesis-KB500USB-BLK-Advantage-Contour...

Be sure to get the Mac one if you're on osx.

One of the best purchases that I have ever made is the Kinesis Advantage keyboard.[1] In fairness, I was tempted to return it shortly after purchasing, but opted to give it one full week of use before making my decision. It took a couple days to become comfortable using it, and now I can't think of myself using another keyboard. It's designed for optimal physical placement of ctrl, alt, delete, backspace, and spacebar, among other keys.

I tried almost everything listed on that page. Far and away, the most effective thing was to just buy a keyboard that puts CTRL and ALT under my thumb instead. The Kinesis Advantage is the most popular and I love mine:

I was in a training class yesterday and had to use my laptop keyboard for the whole day. Halfway through, my left hand was cramping arthritically and it renewed my faith that this was an important purchase.

Yeah, I also recommend a mechanical keyboard:

Kinesis Advantage MPC, with the recessed keys. Here's a picture of me with the keyboard: http://www.railsonmaui.com/about/

It's very important that the keyboard is low enough so your wrists are straight. In other words, avoid putting it on top of a high desk.

I've been using this keyboard since working with Richard Williamson and Paul King at Infoscape in in 1997. It does take some getting used to, and you might want to configure the location of some of the keys. I have all the mac modifier keys accessible to my thumbs on BOTH sides so that I hit the modifier with one hand and use the opposite hand for the key, almost always.

I type on a mechanical, though non-ergonomic keyboard, and like it quite a lot. Specifically a DAS Keyboard Ultimate with Cherry Blue switches. I added o-rings to quiet the report of the click a bit. I have not had tying discomfort in a couple of years since switching to Dvorak layout and going with a mechanical keyboard.

That said. I am not an RSI expert, and can only say anecdotally what I have personally come to like.

I know at least a couple of developers who swear by the Kenisis Advantage - http://www.amazon.com/Kinesis-KB500USB-BLK-Advantage-Contour.... It's a bit pricey, but is apparently a true ergonomic option.

For a straight up nice mechanical with o-rings already installed, the Code Keyboard from WASD is a nice option - see http://codekeyboards.com/.
