Kno is a start-up that is just about two years old, but is already working with tons of e-books to make them even better. If you are toying with buying e-books, you can see what is starting to be out there. In the above video, one sees how a journal is kept of pictures and notes the student takes so that one does not need to go back to each page. Additionally a new feature allows students to quiz themselves on any picture that includes text. As I tell my students and their parents e-books do not equal textbooks. Above is proof.
