Stenographers use chorded keyboards, but the demand for speed is much higher. I think the primary concern is that typing speed simply isn't the bottleneck for most users. The learning curve for a regular keyboard might level off earlier, but few really need typing speeds in excess of what's attainable on a keyboard. What's surprising, though, is that nobody sells a chorded keyboard for cellphones.
