You still have to consider the muscle strain involved in the round trip from your eyes to your fingers.
When typing, you don't really wait for the text to show up on screen before going on to the next letter, and chances are you're hitting backspace before you recognize the letters because you already know you screwed up.
With this interface, you'll have no such luck. You'll type slower, have more errors, and also have muscle strain from not having a more immediate response.
