It's silly they only compared it to a normal on-screen keyboard and not any other input methods, predictive or not (Swype, etc.).
It should be also be noted that their speech tests were done in a controlled, silent environment. I'd expect the error rate and time to complete a phrase would dramatically increase in a noisy room.
