E-books

I knew E-book first in the last class. I like reading books and paper book because we can write down what we think in the blank. Therefore, I preferred the paper book to E-book after reading about E-book. However, I knew E-book can write in some letters with ease after the research about it. And my anxiety has disappear. I think it very useful to use E-book instead of paper book because E-mail play the role as same paper book now. If the price of the digital book has been down and the variety of the book has increased, I would like to utilize E-book by all means.
