I love this and I'm super glad it's being developed, but I think I'd have to break my arm or hand (or have severe RSI) to really dive in. The startup cost seems high, mentally speaking.
I agree, but so is the start up cost of so many other tools people use such as emacs/vim, dvorak/colemak, chorded keyboards, etc.
That being said, I think the biggest limiter is the fact that you can only really use this if you work from home alone, can't imagine using this anywhere outside or at the office.
