I don't really understand why people want such tiny keyboards.
The most comfortable (and healthy!) way to type is to have your hands a shoulderwidth apart so you don't have to compress your arms. I used an ergodox infinity for a while which was fantastic in terms of back pain but terrible in terms of everything else.
I currently use a Kinesis Advantage 1 which I'm tempted to dremel in half so I can get proper separation. It's that or learn how the Dactyl is configured so I can add enough keys to it to be useful :/
