If I recall correctly, Windows sort of stumbled into accessibility as far as keyboard controls because early Windows machines didn't have a mouse. So they had to work pretty hard at making sure every menu and widget was usable from the keyboard, at least until the user got tired of it and went out to but one of those fancy rodents. Apple shipped the whole package of OS, computer and mouse. So they never had to deal with full keyboard control as a barrier to entry for any substantial part of their user population. In some ways they have the advantage of years of hindsight and a clean slate. If you were to do it all over again from scratch, how would you make a GUI accessible? Microsoft may have "invented accessibility standards" with their keyboard controls and later with MSAA, but I think Apple did a lot of things in a novel and better way. The whole idea of drilling down through a UI or content by interacting is pretty intuitive if you're not trained to think through everything linearly. Some of the limits of linear navigation can be reduced with jumping around to landmarks or search, but linear just doesn't scale well as things become more complex. Get me to the right building, then the right floor, then hall, then room, then chair. It's a hierarchy of information and if structured well I can ignore lots of distractions because they fall outside my context of interest. Apple's navigation works in a similar manner and once up to speed (both myself and the implementation), will be easier to use with lower cognitive load.
