John beat me to the punch here. We're thinking about a much more general mobile strategy. My personal mission is to try to design an experience for content, student interaction, and exercises that is usable on smaller screens because, although the tablet market is booming (thanks in great part to the growth of the iPad) the smartphone market is much bigger and growing more quickly. They are also likely to become commoditized more quickly (if you want to argue that they aren't there already). In any case, replace the word "iPad" in his post with "mobile" and I think you are closer to what John, I, and the rest of the team are talking about.
