If you were designing a computer operating system from the ground up for blind people, what would that be like? You'd probably have to ask a blind person to help you, or blindfold yourself while you worked on it. Watching Tommy Edison using his Mac with the help of the screen narrator was like watching him fumble around in the dark. He was able to do it, but it was clearly blind-enabled as an afterthought to the primary design. Computers are about the one place where you'd think he would be able to find a level playing field, but all our normal desktop operating systems, software and websites are built assuming you have vision.
An operating system built for blind people would be - should be completely different to any existing desktop OS of today, just as a phone for blind people needs to be something better than stock Android on a featureless glass touch screen with an assistant to read out what you're doing.

PS - I've seen a blind man using a touch-screen phone on the train.
PPS - It did not seem easy for him.
