In the article "The Answer For Textbook Publishers" by David Warlick, he says that textbooks should be smaller, or digital so it can be put on an Iphone or Ipod. I think this would be a grat idea because textbooks are very large and heavy. It would be nice not to have to lug those giant books around. Having it in my pocket would be such a conveniance. Overall I agree with what he is saying and think this is a great article.
