If I could offer an analogy, the world of academic journals has been totally transformed by digital availability. As a post-grad and (briefly) lecturer I traipsed around all the libraries I could get access to, tracking down specific issues of the Cambridge Archaeological Review or Hermathena or whatever, or waited endlessly on inter-library loans so I could spend my evenings photocopying relevant articles. Now I don't need to go near a library for most of my needs, once I can my hands on a JSTOR subscription (over 1000 journals - not 1000 issues, but whole runs). However, while I use a rake of online resources, I (personally) still prefer to read hardcopy and annotate photocopy, and I prefer to do both in a nice peaceful built-for-purpose library, whch often has the advantage of books that aren't available, and confronts me with books I'd never have thought of looking for. I note that most of the young folk don't seem to have this ingrained taste. And it'll be the same with comics and tablets/psychic paper.
