Online Textbooks vs. Paper Textbooks

As long as people have been going to formal school there have always been paper textbooks used in teaching kids in school. Now, years later, that we have made new technologies and new ways in which you can use them, I ask you which do you prefer? I only recently started buying my textbooks on my Kindle in online versions. I believe that there are good and bad things to both types of books. One down side to online books is that not everybody can have access to a computer or tablet or smart phone to be able to read their textbooks. There is an up side though, with online books you have more access to tools like a dictionary right there in the book and other tabs where you can write notes right in the spot where you need them. Sure you can do this with a paper textbook but you have to have a separate piece of paper for the notes, with the online book everything is right there all in one place. Now with paper textbooks they are easier for everybody to get. They're always going to be around, because people are never going to stop printing books. But one big down side for these kind of textbooks are the prices of each textbook. Online books are always cheaper then paperback textbooks, that's one reason why I started buying my books on my Kindle because i was tired of spending so much money. Also my Kindle isn't as hard on my back as paper textbooks are.
