When it rains, it pours and information is pouring out about the rumored “super-sized” Amazon Kindle. The upcoming Kindle, now known as the Kindle DX, will pack a full-featured 9.7-inch electronic ink display, 5-way navigation button and a QWERTY keyboard into its large white housing. It basically looks like the designers took a Kindle 2 and stretched its screen from 6 inches to 9.7 inches, and then squished the keyboard in the process. The new Kindle DX will reportedly feature an improved web browser, the ability to add annotations in addition to notes and highlights and a long awaited native PDF reader. In addition to newspaper and periodicals, the Kindle DX is designed to support textbooks and, according to the Wall Street Journal, a special edition packed with pre-installed textbooks for chemistry, computer science and a freshman seminar is being released as part of a college trial. Lev Gonick, chief information officer for Case Western Reserve University, claims that a lucky bunch of select college students at Case Western Reserve, as well as Pace, Princeton, Reed, Arizona State, and the Darden School at the University of Virginia are signed up to test out this new device starting in the Fall semester. Sweet! Hit the jump for a few blurry images of the Kindle DX seemingly snagged from a slide show presentation.
