E-books are recommended nowadays and I saw a number of students buy them. According to them, e-books are easy to carry around and read as if they were books in the original sense of the word.
As for me, I don't like them. Because reading is not just about eyes following over sentences printed on paper. The act of reading includes flipping of the pages, taking notes on the paper, and so on. Thay is, it is also a matter of bodily activities. But e-books don't allow these movements.
However, today a teacher recommended the students to buy the e-book version of the textbook because he found that it is less expensive and available as soon as purchased. As I am a student with insufficient time and money, there was no reason to refuse to buy the e-book.
