The smell of a good book?
One day soon I envision my children curling up to an ancient book on their lap. It will not have the smell of leather, its pages will never curl, and I will never have to worry about them tearing the pages. They will scroll down the pages with the PGUP or PGDN button and they will be able to zoom the text to their own preference and I will have to still worry about them having food and liquids near the books.
I am a post modernist and I accept this change. I also know the price was once high for this book and now it is free for the download. I will still go to the library for flip page books, and I will support good writers; however, like MP3s for music, books are changing and the big box book stores must adapt to this change or die.
