Read actual books! Because, what if you run out of battery, will you just have to stop reading? With actual books, you can read for however long you want. And what if something goes wrong with the Kindle, like it breaks or something? With actual books, you can't "break" a book, you can tear a page but you can just tape it back.
Books are meant to be read on paper, not a screen. That's how it always has been until the invention of e-books which are silly. Don't we people get enough screens and buttons in our lives? Why must we read books on screens, that's like the only thing left that people read on paper. Hell, even newspapers are starting to go down because people read the news on their computers.

Reading books on screen makes it easy and I can easily flip around pages and websites at will and can save any information for retrieval any time, any where. So these make reading books on screens more attractive.
