I think E-book is very convenient because we can buy books that we want to read everytime and everywhere and it does not take much space. And it is also good for the environment, for it does not use paper and ink, needs only electricity!
However, we cannot enjoy the texture of the book when we read with E-book, I think turning pages and touching paper are one of the enjoyment of reading books.
But I want to have one. It's really convenient!!!
