Recently Stephen King, one of the best known American writers, wrote a very good article about his recently bought Kindle.
Will Kindles replace books? No. And not just because books furnish a room, either. There's a permanence to books that underlines the importance of the ideas and the stories we find inside them; books solidify an otherwise fragile medium.
But can a Kindle enrich any reader's life? My own experience — so far limited to 1.5 books, I'll admit — suggests that it can. For a while I was very aware that I was looking at a screen and bopping a button instead of turning pages. Then the story simply swallowed me, as the good ones always do. I wasn't thinking about my Kindle anymore; I was rooting for someone to stop the evil Lady Powerstock. It became about the message instead of the medium, and that's the way it's supposed to be.
And did I mention that you can also look up definitions of words that puzzle you as you read? My definition of Kindle: a gadget with stories hiding inside it. What's wrong with that?
