This isn't to negate the fact that there have been times when I've been tickled to find a page I needed scanned in on Google, or when as a distance learner I've been able to read entire volumes while at home
Interestingly enough, I own an e-book reader. Oh, not a dedicated one--but I have a Dell Axim Pocket PC that we bought a few years ago... I think it was 2002. I primarily used it to write my thesis and other grad school homework/research--basically it was like a mini-laptop that I could carry in my purse. I eventually stopped using it because 1) I got a "real" laptop in 2005, 2) I started editing images a lot, and 3) the built-in battery lost its "oomph" after three years. But while I had it, it was handy not only for homework, but it was a handy-dandy e-book reader, too. I downloaded scads of public-domain stuff like Little Women and Ivanhoe, and it was nice to always have a wide selection of reading available in my purse. The back-lit screen also provided a nice solution for reading in bed at night. But if I was at home or at work and print books were handy, I always turned to them. I see ebooks and ebook readers as tools of necessity (or of necessary convenience), but not of pleasure.
Anyway, I don't need to re-state Rob's arguments here--I suggest reading his blog post. But I think it's worth noting, from a "Librarian for Digital Collections" who is a tech junkie and Library 2.0 fan, that sometimes the old-tech solutions are really the most practical.
Plus, as noted ad-infinitum elsewhere, bibliophiles like myself can't get over the feel, look, smell, and other tangibility of books. Until that's somehow available electronically, give me print instead.
