Today, i wanna talk about the e-books.
If you have e-books, you do not need bring many heavy books all the time because e-books were insered in your mobile phone.
i think they are very convenient, however i do think they have also demerits. Relying on e-books would make your eye sights bad. Also, you would not be able to get the old smell of paper books!! i really like it.
i think the most proper way to use e-books is to use them sometimes but not to depend on them too much.
