Insightful comment, thanks for giving a perspective from a completely different profession. :)

There is however something i need to point out to you: Chording is not for fast typing. In fact, since you must hit multiple keys either sequentially or together, just to produce a single signal to the computer, it is guaranteed to be slower. However chorded keyboards would make it possible to type in restricted situations, such as people who are hospitalized, missing limbs, working on something where the other hand is occupied or where body motions are limited, on the go, or heck, simply while lying back and relaxing; while still maintaining a useful speed.
