If you are a student with an iPad, you might not need a backpack anymore. According to the WSJ, that’s the way that Apple wants things to be, and Apple is pretty good at getting what it wants. This week, the company that changed the music industry unveiled a plan to get into the electronic textbook gold rush. If you’re a college student living on top ramen after taking out a $20,000 loan every semester, the electronic textbooks that Apple is talking about are good news: “Textbooks for courses such as algebra 1; environmental science and biology will be available first, priced at $14.99 or less.”$14.99 might sound like a lot if you’re in high school, but any STEM major knows that an introductory textbook made out of paper, cardboard and glue can cost upward of $100. That’s a lot of money for books that most professors don’t reference much anyway. Electronic texts don’t have all of the advantages of paper texts: It’s harder to make notes in the margin and easier to get distracted since iTunes is only one click away. But, if nothing else, the $85 you save on Biology 101 might be enough for an upgrade—from ramen to mac-n-cheese.
