Amazon has, as expected, released announced a new large-format Kindle e-book reader:

Amazon.com today introduced Amazon Kindle DX, the new purpose-built reading device that offers Kindle’s revolutionary wireless delivery and massive selection of content with a large 9.7-inch electronic paper display, built-in PDF reader, auto-rotate capability, and storage for up to 3,500 books. More than 275,000 books are now available in the Kindle Store, including 107 of 112 current New York Times Best Sellers. New York Times Bestsellers and New Releases are $9.99 unless marked otherwise. Top U.S. and international magazines and newspapers plus more than 1,500 blogs are also available. Kindle DX is available for pre-order starting today for $489 at http://amazon.com/kindleDX and will ship this summer.

“Personal and professional documents look so good on the big Kindle DX display that you’ll find yourself changing ink-toner cartridges less often,” said Jeff Bezos, Amazon.com Founder and CEO. “Cookbooks, computer books, and textbooks – anything highly formatted – also shine on the Kindle DX. Carry all your documents and your whole library in one slender package.”

Conspicuously missing, of course, is color. And a price cut for the Kindle 2. I can't help but be interested in this, but come on: $500 would get you a killer notebook computer these days. Or 1/3 of a low-end Mac notebook. :)
