Amazon Introduces $489 Large-Screen Kindle

"Now there's a new Kindle for that -- the Kindle DX. Its 9.7-inch screen is 2.5 times the size of a regular Kindle display. That makes it better for reading 8 1/2 x 11 documents, cookbooks, and other formatted material. It has 3.3 GB of storage, enough to hold about 3,500 books. The price: $489. Textbooks are another good application for a wide-screen Kindle. Amazon has partnerships with the three leading textbook publishers -- Pearson, Cengage Learning and Wiley. The new Kindle will allow students to carry smaller backpacks, Bezos says. The cost of these textbooks is unknown, but Bezos says these will likely be priced lower than physical copies."
