Just as with the Kindle 2, Amazon posted the Kindle DX product page while the launch event was underway. Specs-wise, there's not much here we didn't know: the big changes are a larger 9.7-inch screen that rotates to landscape display, a PDF reader, and more storage space at 3.3GB. The big news is actually the flat $489 price tag, which seems on the high-side of realistic to us -- although the subsidy-pricing rumors weren't totally inaccurate, as the New York Times, Washington Post, and Boston Globe will offer subsidized on-contract Kindles to customers who can't get at-home delivery when the DX ships this summer. (Yes, that's a pretty lame restriction.) Amazon's also announcing a wide range of textbook publishing partnerships, with tomes from Addison-Wesley, Wiley Higher Education, Longman & Prentice Hall and many others available -- and what's more, Arizona State, Case Western Reserve, Princeton, Reed, and Darden School of Business at the University of Virginia have all signed on to distribute "hundreds" of Kindle DXs to students this fall. We're hunting for more info, stay tuned.
