Most e-book projections are wrong. They anticipate for every $1 billion lost in the traditional book business that $1 billion will be gained in the e-book business. This ratio is actually closer to 1-to-2 because people are collecting e-books like nuts for the winter. They are easy to buy and download, much like music. And, frankly, it’s fun to fill up your iPad with a colorful, robust set of thumbnails in your library. I don’t know why this is a good feeling, but it is.
