There's something lost from paper to e-ink, and everybody who uses a Kindle will realize that. If e-books become big and cheap, that means book sales are going to benefit, to some degree.
I personally read a lot and I think the electronic medium will add an additional layer of value: annotation, collaboration, access to a large amount of knowledge without having to lug around paper. Print's slowly dying because it's not linked to rest of the content in the world.
I don't think content creators are dead by any means, but I do think there have to be devices and mediums that enable more than the create and publish model.
When Amazon designed Kindle, they tried to make sure the user experience was as close to a book as possible. When I go on a plane, I would prefer not lugging around 4 books in my suitcase vs just using a Kindle. There is something about the print medium that's very pleasing, but I think e-ink and e-books will co-exist like theater and t.v. Although many can say that the T.V. will cannabilze all theater going activity, there is something unique about the experience that the solo activity cannot capture.
