one thing I will say that many may or may not know is that Neil Cavuto has MS. He's had it for many years and coped very well. In fact, he's a hero of mine and an awesome, very smart business guy.
A device like this would/could be very beneficial and useful to someone like him down the road when he's unable to control it. I could see him discussing this technology but I have not seen anything anywhere saying this is happening.
