In his <A HREF="http://www.nytimes.com/2008/06/06/opinion/06krugman.html">New York Times column</A>, Paul Krugman reflects on the the digitization of everything and how this will change the economics of publishing as we know it.
"Basically, the Kindle’s lightness and reflective display mean that it offers a reading experience almost comparable to that of reading a traditional book. This leaves the user free to appreciate the convenience factor: the Kindle can store the text of many books, and when you order a new book, it’s literally in your hands within a couple of minutes.
It’s a good enough package that my guess is that digital readers will soon become common, perhaps even the usual way we read books.
How will this affect the publishing business? Right now, publishers make as much from a Kindle download as they do from the sale of a physical book. But the experience of the music industry suggests that this won’t last: once digital downloads of books become standard, it will be hard for publishers to keep charging traditional prices. "
