Government lawyers failed to learn that industries undergoing massive change brought on by technology are likelier to be flailing for sustainable business models than flouting market power to fix prices. Book publishers are still trying to predict the full impact of technology. As consumer choice widens, some people want beautifully produced printed books, while others want enhanced e-books with video and other graphics. There are e-books selling for 99 cents and others at premium prices. Perhaps a hardcover should come with access to digital versions. Contrary to the assumption by government lawyers, there's no reason to think the price of e-books must be $9.99.
