The rumored larger-screened Kindle just had some basic specs leak out. The Kindle DX is rumored to have a 9.7-inch screen, the ability to add annotations and PDF support. Looks like this Kindle DX is designed to appeal to students and textbook publishers. The Wall Street Journal reports that some chemistry and computer science students at various American universities will receive the new textbook-friendly Kindle.
Some that have been specifically named so far are Case Western, Pace, Princeton, Reed, Darden School at the University of Virginia, and Arizona State. Apparently it also includes an actual functional web browser.
