Yes, that makes perfect sense. Apologies for the overly negative tone of my comment.

Do you have a description of the device with specs, or is it in earlier development than that?

Are you using the technology from DotPad, or do you have your own?

Does it have a Braille keyboard for input? I would consider that essential for education.

I fully agree that education is the most important thing. Without it Braille will die. In the UK blind schools are dying out, replaced by specialist teachers who visit mainstream schools. It's just not the same and children don't have much incentive to learn Braille.
