It's now a question for the book market, with the digital book downloads on products such as the iPad and Kindle, what to do with their prices. If prices are high in the beginning, they will be adopted more easily than if they were raised later in the digital adoption period. As goes for any product, it's easier to launch a product at a high price and lower it than try to raise it once consumers have gotten accustomed to the lower price point.
