I bought an e-book reader for several reasons listed on the poll (free ebooks, portability, availability, ...) but one the main reason is that I never liked paper books (or things written on paper) too much.
The font is not resizable, if you often carry them with you they get damaged, you risk to lose them (maybe it's just me
), and a lot of other issues.
Moreover I really like the opportunity to separate the content from the form and I'm pretty happy to be part of this "revolution".
