The interactive storybook app is also available for Xmas gift-giving by Windows 8 parents, but they'll pay $4.99 for a version that lacks the features available in the $0.99 iOS version. Which raises some interesting questions: 1. As concerns are being raised over a new Digital Content Divide, is it cool to have owners of the cheapest computers pay 5x the price charged to the most elite consumers, especially for an inferior port of an existing app from the same vendor? 2. Why exactly does a port of an existing app have to be sold at a price which so vastly exceeds that of the original — is it mostly due to economies of scale, difficulties of cross-system app development, or pricing shenanigans?
