The first OS and computer that is fully accessible out of the box. http://www.apple.com/macosx/universal-access/

I can't believe it has been considered important enough to be one of the major features of Snow Leopard, I am so happy for the blind and visually impaired. They did it with the new iPhone the first commercialized accessible touchscreen and they are doing it again with the new Mac OS. Apple is the most innovative tech company there is no doubt about it.
