This wouldn't be an issue if industry was held up to the same standards of government, i.e. B&N had to make their reader accessible for the visually impaired. It wouldn't even place a huge burden upon industry since they are only being asked to implement software based solutions. Even if there are royalties on that software, standard units could be shipped without it and accessible units could be shipped with it.

The thing is, the computer industry decided to disregard the enabling aspects of their technologies and focus upon features that weren't universally accessible in the early days.
