As a long time RSI-sufferer that has tried everything I can confirm the KeyboardIO was also very nice... but nothing beats Kinesis Advantage. I think it's the domed arrangement as I did feel the thumb arrangement on the KeyboardIO was superior.

I've bought a Kinesis Advantage about every three years since 2003 (I think). Still the best keyboard out there despite being USB-A and the lack of bluetooth. I really want to like the Kinesis 360, but the lack of a function key row keeps me from buying one.
