E-books

It is much easier and quicker to search for passages now, and we can also write notes in an e-book. What is more, they save a lot of paper. But e-book readers are still more expensive than paper books, so not all people can afford them. However, with the rapid development of electronic technology, reading e-books will become cheaper and cheaper. A lot of people think there will be more e-books than paper books in the near future.
