I forgot to write about e-book, so I'd like to talk about it.
I like reading a book, so I'm interested in e-book.
It is convenience for us because we do not need to carry heavy books and we can get a book whenever we want.
Therefore, it will be popular to use e-book in many countries, but in fact, I like smell of books, and weight of books give me a feeling of achievement when I finish reading.
The service of e-book is very convenience, but also I want a paper of book not to decrease.
