What seemed so elusive yesterday is now concrete. The Amazon Kindle DX is indeed a real product, complete with legitimate pictures, pricing and a tentative release window. Its 9.7-inch screen can be turned to landscape mode, capacity is increased to 3.3 GB and there’s a PDF reader built in. At $489 dollars, subsidies from the New York Times, the Washington Post and the Boston Globe (if it survives) sound attractive, but there’s a catch: Only customers who can’t get delivery at home can take part in the deal. Mostly, the new Kindle seems geared towards textbooks, with several major publishers signing on and five universities (Arizona State, Case Western Reserve, Princeton, Reed, and Darden School of Business at the University of Virginia) agreeing to hand out “hundreds” of the devices to students in the fall. The rest of us can pick up the Kindle DX this summer. [via Engadget]
