What's the point of a bookshelf full of books other than as an antiquated trophy case of written ideas trapped in awkward, temporary physical relics?
The Internet will not kill the book. But it will change their form permanently; books are no longer pages printed with atoms, they're files printed with bits: eBooks.
To make it worthwhile, I believe publishers need to do two things: eBooks should be inexpensive and eBooks should be a near-perfect replica of the print book.
Generally the experience is good. For books that are entirely text, with very little layout, the various eBook formats do a great job [but the layout of more visual books sometimes gets distorted]
