It would be very difficult to think of an E-book as precious. I say this on the understanding that nothing of unlimited supply can really be thought of as precious. The hand illustrated, hand written manuscript would be unique. An edition of a printed book would be limited to a particular number of books. But take something like A Windral and there are trillions and trillions of copies available. Such a shame A Windral isn't edible.
Then there's the argument that insists the content of an E-book might be worth
reading. A tricky area for a writer of E-pulp who might find himself tempted by
the idea of what the professionals call Decorative Accents. You can't just leave
an E-book lying around on the coffee table or the beach blanket. Certainly you
can leave the E-book reading device lying around, hang it on the wall next to
the Picasso, but not the E-book itself. It's an extraordinary progress, and yet
nothing has actually changed since long before Homer.
