Motoko Rich, also in the NYTimes.com:

At a glance, it appears the e-book is more profitable. But publishers point out that e-books still represent a small sliver of total sales, from 3 to 5 percent. If e-book sales start to replace some hardcover sales, the publishers say, they will still have many of the fixed costs associated with print editions, like warehouse space, but they will be spread among fewer print copies.

Nobody said innovation is fair - it’s efficient.
