Normally I am bearish on this type of technology, given the number of previous similar attempts with similar marketing that all failed to deliver. This line gave me pause, though:

"Within just a few seconds, moving the cursor with thought became almost second nature, and I was able to steer it up, down, and to the left and write by thinking about moving — but not actually moving — my hand."

That's quite a strong statement. If true, I'd hop on that bandwagon.
