I've heard about the new e-books. How are they different from regular books?

The main difference is that an e-book is a digital version of a book, which means it can be read on any device with internet access. This includes smartphones and tablets. Another difference is that e-books usually have fewer pages than traditional paper books, since they're easier to store and carry around. E-books also tend to be more expensive than physical books, as publishers must pay for the production costs of each copy. Finally, e-books often include extra features like audio, video, and interactive elements.
