I am not sure of that. This might be fueled by a lot of negativity, but many people I know care 0 about ergonomic reasons, even if it fucks up their body while working. Chair too low, not configured, table not at the correct height, although easily changeable... I could go on. Also, I am not sure how this thing makes anything better: you still have to do hand movements correctly and most people will need some kind of surface to orient their hands on. Same problem, without a keyboard.
