Amazon’s latest Kindle is the just-announced bigger version of the Kindle2, the
Kindle DX. With 9.7″ of screen real estate, compared to the Kindle 2’s 6″, it theoretically provides a better reading experience for large-format publications, primarily textbooks, newspapers, and magazines. You can pre-order it today for $489, $130 more than the regular Kindle2.

Other advantages of the Kindle DX over the Kindle 2 include 3.3Gb of Storage for 3,500 books, rotation settings for orienting it in different reading positions, and most usefully, native PDF support. That last one is the only thing I really care about–although I’ve heard that the larger screen size will make refreshes slower. And, what about international support, faster refreshes, or color e-ink?

Still, for Amazon, for every 100 hard copies sold, an additional 35 Kindle editions are being sold, which is incredible growth. For more opinions, try searching Twitter for “Kindle DX”!
