e-Book sales top paperback books

I read at CNN today that ebooks beat paperbacks. I'm an avid reader. I love my amazon kindle. I find it easier to read a novel on the kindle. I am a graduate student in a mental health counseling program. I've downloaded most of my text books on the kindle. It saves money to do so. However, not all college text books are on the kindle. There are some books I'd rather have in print. I buy children's picture books because I work with children. I give them as donations to the children's library where I work at. I want to encourage them to be readers. I like to have my favorite books in print, too. I also read some graphic novels, which I get in paperback, like the Max Ride Series.
