I met a blind person studying computer science. I asked him why he used a speech synthesiser instead of a Braille display and he replied that he'd love to have a Braille display but they are far too expensive for a mere student. (The sounds that emerged from his speech synthesiser didn't much resemble human speech but he was used to it and it was obviously quite a lot faster than normal human speech.)
