Paul Krugman on E-Book

Noted economist Paul Krugman recently offered his prognosis on E-book in New York Times:

Now, e-books have been the coming, but somehow not yet arrived, thing for a very long time . . . if e-books become the norm, the publishing industry as we know it may wither away. Books may end up serving mainly as promotional material for authors’ other activities, such as live readings with paid admission . . . Bit by bit, everything that can be digitized will be digitized, making intellectual property ever easier to copy and ever harder to sell for more than a nominal price. And we’ll have to find business and economic models that take this reality into account.
