Norman, Smart phones are, indeed, a great example of universal design principles -- and getting better all the time. When it comes to mobile devices, Apple is still "king" with its IOS devices (iPhone, iPad, iPod) because they all come with built in accessibility (through Voiceover). The Android-based devices are catching up with the development of some newly available applications, but the fact that Voiceover is built in to the IOS devices means that it operates more smoothly in conjunction with other apps.
