Books are now being produced in electronic format which can be read on a PC, an e-reader, a tablet,

E-books are published and produced a lot due to the convinence. It is easy to purchase, read and carry. Although, it has a lot of advantages, there are few cons. Some people get eye strain from e-books because it is usually a small device which has bright screen. In addition, it\'s quite difficult to focus on the stories. I always read same story again and again because of the small letter and the light. However, some people prefer to buy E-books because it is cheper than paper books and it doesn\'t need to store in the book shelf. People can access their E-books regradless of time and place. I used to read E-books but I prefer to read a book with paper recently. I think both have pros and cons but the most important thing is having a habit to read books. It helps people to improve their skill anyway.
