I've used over a dozen split- and ergonomic- keyboard over the years, so I am familiar with the time investment. And I do agree, for the most part, that the time is well invested up until a point. But I don't see how requiring additional simultaneous keypresses is "more ergonomic" than pressing a dedicated Ctrl or Alt key. Airplanes, which pilots invest much time learning to fly, have dedicated buttons for all functionality. How is "ergonomic" defined in this context?
I'm not arguing, really I'm asking to hear the answer and become wiser.
