"Print is dead."
-Dr. Egon Spengler, 1984 (look it up)
I think we should all give up on the idea that, in the future, people won't be able to read. They'll have to read! If they can't read, they can't learn... if they can't learn, they can't become engineers and scientists... if there are no engineers and scientists, we sure as hell won't have any e-book readers around!
People still need to read, in order to function in the society we've been grooming for the past 3000 years.
Now, making sure they
enjoy it requires compelling content. I think the content is there, though it needs expansion (more e-magazines and e-newspapers, for example... print mags and print-and-online newspapers are enjoying successful sales now, and I think their e-versions will ultimately sell better than e-fiction), leaving DRM and price as the only real hurdles here.
