I am a long-time kinesis user because I find the kinesis i the best combination of speed and comfort. But once I head really crippling RSI, I switched to the safetype keyboard (www.safetype.com) for a few weeks, and found it even more comfortable. Eventually I switched back to the kinesis because of the speed and accuracy, but the safetype is worth a try if you have really bad pains.
