I've found that there are a number of different prescriptions for RSI pain, and that you have to experiment until you find what works for you. But that's complicated by the fact that it's hard to run experiments on yourself because there are so many confounding variables.
In any event, to add to the anecdata, someone below recommends not resting your arms/wrists on anything and letting your hands float above the keyboard. I've tried this, and the small muscles in my back that keep the arms lifted would become sore bundles of fire that eventually would spread pain throughout my back/neck/arms/wrists.
I found, paradoxically, that totally resting my arms splayed wide on my desk combined with a Kinesis Freestyle so I can keep my wrists straight (this wouldn't work with a regular keyboard) is the ideal setup for me.[1]
Not saying this would work for everyone.
[1] I have a standing desk combined with a high chair oriented such that the desk comes a bit higher on my chest than a sitting desk would, such that I can just rest my arms on the desk. The keyboard is not elevated and is basically flat to the desk surface, and is separated and angled such that my wrists are not bent.
