I read somewhere a bunch of people (teenagers / college students) saying that they could type at normal speed on iPad glass keyboards, so I did an experiment and with no practice could achieve over 40wpm (and I suck -- I get about 60wpm on a "proper" keyboard, which is fine since I don't compose prose or code faster than that). I suspect that it's partially an acclimatization issue, and getting over the hump just requires time. (My "hump" for getting to be as productive with a trackpad as with a mouse, by comparison, was about 12 years...)
