As a bookworm, this attitude has always bothered me. I know few pleasures as glorious as taking a shiny new book, running your hands over it, smelling that new-book smell, and settling into bed for an evening of reading. I just don't believe you can get the same aesthetic pleasure from your e-book reader, no matter how convenient it is.
But as a librarian and document delivery specialist, I can say one thing for damn sure: Books will never be obsolete as long as there are all these damn broken links on the web.
(I will add that generally, government websites are the worst offenders, and have the least user-friendly websites to boot.)
