Even the free-form mode 75 character per minute sounds amazingly fast for a thought interface.
I wonder what it's like to use. I know there have been many attempts at this, and they're steadily improving, but I watched a talk at EvoMusArt 2007 where researchers used a smaller array of cranial electrodes to have the user control a mouse. That it worked blew my mind. But they talked about how slow and noisy it was to get the cursor from one side to the other... maybe a minute IIRC. What I remember most distinctly was the researcher said it was physically draining to do, that after 5-7 minutes of this activity they would be sweating and exhausted, without moving.
