I might be misunderstanding, but are you talking solely about the most here? I'm mostly curious about the chorded "keyboard"(?) as an input device - have you spent time with it as a daily driver? How does it compare to a traditional keyboard? I would guess a keyboard would be easier for a beginner, because ~1 key per symbol, and the keycaps are all printed (though I'm sure many of us remember our untrained selves scanning the entire keyboard intently, looking for whatever letter had eluded us) - so chorded input would be more of a learning wall than a learning curve, but once that's achieved... is chorded input ~100% speed of a QWERTY kb, or 10%, or 150%? Is it more or less tiring, physically and mentally? Very interested in your experience.
