Michael, I understand that there are people who will need and use all the functionality of the braille note and gps. But students, at least, are often in the lucky position to have their technology bought and paid for by an agency. this is great, but for people who don't have that possibility, the cost of the equipment is daunting. There is a market out there, I am convinced, for people who would like and use full featured gps but who can't justify the additional cost of the braille note to run it on. Mary
