Economics isn't the primary issue for many (Score 1)

Granted that the motivation for ebooks will be different for different people but at this point the economics doesn't really make sense. The issue for many of us is convenience and access to material. The ability to have near instant access to a variety of new reading materials (books, magazines, newspapers) at my fingertips no matter where I am AND in a small and easy to use form factor is the driving factor. I make 2-3 cross-country round trips monthly by air. The ability to access newspapers, magazines, and new books just before getting on the plane and always have them in the same form factor is very convenient. At home, the ability to carry the unit and access the magazines and newspapers whenever I have a few free minutes is also very valuable. I just wish there were more newspaper and magazine content available for it. (By the way, I see at least one other person with a Kindle or other ebook on just about every flight sitting near me so I know there are a lot more out there).
