One example is art, from scratches in the wall of a cave to the electronic pixels on a computer.

Books. Slower in evolving began as symbols and pictures telling a story to again, the electronic words on a screen. E-Books are popular now and growing at an accelerated pace. Very soon they will top the traditional bound paper books. Already e-books have topped sales of hardback books.

However, I believe there will always be readers who will want their favorite novels in hand. To hold the volume, feel the pages and smell the print, to me is heaven as it is with all readers.

With e-books a reader can save money. Download several and take their time reading them. When one in particular grabs the reader and they can't live without it, I suggest you could purchase the book to have in your own personal library. I would recommend hardbacks. They last longer and give an elegant appearance on your shelf.

E-Books are the future and the future is here, now.
