[B]ooks sold on the Kindle are now outpacing the hardcover books Amazon sells. In the past three months, for every 100 hardcover books sold, Amazon.com has sold 143 Kindle books, they say. And that gap is getting wider. In the past month, for every 100 hardcover books sold, there have been 180 Kindle books sold through Amazon. This is across Amazon’s entire U.S. book business and even includes hardcovers that have no Kindle version. Plus, free Kindle books are not included, or the numbers would be even higher.

Part of the sales growth can be attributed to the Kindle's price drop—from $259 to $189—which Amazon founder Jeff Bezos credits as a tipping point for the device.
Do you think we're closing in on a time when the majority books will be published exclusively as e-books?
