Let's be clear about something here: We're only talking about
two universities, not "all" or even "most" who are doing ebook pilot programs. And the lawsuit has been around for a few months now.
If the relevant course materials are made available to the disabled students in a timely fashion, then I don't see any discrimination. (If that isn't happening though, then I'd concur there is a potential problem.) And at the risk of being too platform-specific

, presumably once the Kindle app runs on Macs, which has a built-in "Speech" software that converts text into speech, then all the advantages of a Kindle are pretty much available to the disabled students. I assume Windows has similar software available, but it's not built into the OS as far as I can tell.
I think it makes sense to pressure Amazon to make their devices easier for the disabled to use, but I still don't think a lawsuit that accuses various entities of discrimination is the optimal way to proceed.
