Text books or Digital Books...Which one do you prefer??

I wasn't into e-books until I got a Kindle! Now I don't read anything else! I hate reading on LCD screens because it's a major strain on my eyes, so I had no interest in e-books at all. But the new electronic ink technology is absolutely amazing! The Kindle definitely changed the way I read, and I read so much more often now! If you love to read, I'd definitely recommend getting one!

Digit books with the advantage of convenience and cheapness are quite popular with young people,but I still prefer text books.When I read a text book,I can put all my attention into the book,and feel that I am studying,but when I read a digit book,I can't fix my attention to the book,and always feel that I am playing.Maybe this is just because I fail to adjust myself to it.However,there are also some disadvantages of digit books,for example,facing computer for a long time would harm your eyes.
