Most ebook readers use e-ink screens, which don't need to be backlit to be legible (nor do they need power to maintain an image, only to change it). So they are more comfortable to read for long periods than a regular LCD screen. (Not that I have any problems with staring at a screen for hours, heh.)
I don't see why books should be given any particular exemption from the march of technology any more than anything else should. There'll always be a market for books, in the same way there's still a market for vinyl records. It'll probably become such that the dedicated fans buy their signed, printed books, and the rest read ebooks; maybe you get a few books you really love on paper or something like that. Ebooks wouldn't sell if there weren't good reasons for people to want them rather than paper books.
And I have precisely zero sympathy for the plight of the newspapers. They're failing because they screwed up. I read the news on my computer every morning, and it's way less annoying than fighting with a newspaper, plus it's way easier to find and read the stories I'm interested in. Newspapers fill their pages with sensationalism and vacuous nonsense, and are frequently shown up by blogs for a complete lack of actual journalistic fact checking, despite so frequently going on about the respectability of old-school newspapers. Fun fact: You don't deserve it and so you lost it.
Technology allows us to do wonderful things, and it's senseless to try and preserve outdated methods solely for old times' sake. Where they have their advantages, then work to these strengths; where they don't they will die.
