Interesting to read all your thoughtful comments. I haven't read 50 shades... I know many readers have enjoyed it, but it wouldn't be for me. There are so many books I want to read, and too little time!
I, too, love real books, and can't resist buying them, but the kindle is great for holidays. I have the app on my IPad, which I find easier to navigate than the kindle. Another thing I love about it is that I can read a review or hear a recommendation, and get the book on the kindle immediately. I'm currently reading Elizabeth Taylor (the novelist, not the actor) - wonderful!
