I too like the idea of changing the shape of the letter keys. Also, if I were to decide that 2 Book Ports were better than 1, I would vote for the removable belt clip. I have another device that I carry in my pocket and removing the belt clip on it certainly makes a difference. Of course, it would also help when using it as a note taker if I ever learn computer Braille. Make it a grate one Sharon F.
