With the huge growth of e-books and the swarm of e-book devices that are coming out, everyone in publishing is interested. Many acknowledge that it's the future, even if people continue to use paper to some extent for a long long time to come.
But I've always assumed it was better to have e-book reader software and then ad books. This article got me thinking... what would it be like if the book was a whole app, and is there anyone that would prefer that approach? (It definitely would be simpler for the casual reader, even if it would annoy the advanced user.)
