I personally prefer a regular book, I have a collection of them.
However, I think saying that E-books are damaging society is taking it a bit far. It's also a little bit annoying that people are like "OMG Luddite" whenever someone wants us to think about the effects of advancing technology. It really is a little scary to think that a book can be altered whenever you plug in the reader or whatever, but technology advances. You can't stop the advancement of technology, and it's stupid to try. (If you want to look to the Luddites go ahead, factories and machines still exist, they didn't stop much of anything.)
However, I'll keep getting physical books as long as they keep making them, but I may get the same book on E-reader as well. Enjoying the classic does not mean denying the future.
