Weird iPhone Book-in-an-App Category Pricing: Why Buy "The Lost Symbol" for $24.95 When the Kindle Version is $9.99?

Apps for the iPhone are, in general, much lower in price than apps for other phones and conventional computers. We’ll all become accustomed to the 99 cent to $4.99 price range since the iTunes App Store opened in the summer of 2008. There is, however, one iPhone app category that defies this price norm: The book-in-an-app. These are books that are wrapped up and delivered as an individual application. You buy, download, and install it like any other app.
