"Run a test. Give a 5-year-old a printed book and an iPad and see what happens. That 5-year-old is going to go right for the iPad. They're not intimidated by it. They know what to do with it. They'll start searching around. And in a children's e-book, you can have links to kid-safe encyclopedia. So if they click on the lion, it takes them to Africa and tells them all about lions. So now, the e-book is educational."
