Here is a website that posted the “Best Interactive iPad Books of 2011 for Adults.” While interactive books for younger audiences are coming out in droves, interactive books for adults are not so hard to come by. According to the article, this sector is under-reviewed and the products can be very costly making it difficult for consumers to decide which book-app is the right choice for them. The website lists these as the best interactive books for 2011: Our Choice, The Last Supper, History of Jazz, The Waste Land, Man in Space, On the Way to Woodstock, and Here on Earth.
