It's reported that students in Korea have used e-books from 2011. There are some people suggesting thate-booksshould be popularized in our country.Some people strongly support of it, but some others are against of it. In my point of view, I prefer the latter. First, as we all know that our society develops unbalanced. Some poor areas can't afford the costs of e-books. Furthermore, reading the e-books for long a long time will do harm to the eyesight of students. Last, the traditional books of paper have many advantages over e-books.
