Amazon.com founder Jeff Bezos displayed the Kindle 2 at a recent New York press conference. The device has a 6-inch, 600 x 800 pixel display that provides 16 shades of gray, an upgrade from its predecessor that only displayed four. The company claims that pages refresh 20 percent faster in the new version of the device, and the Kindle 2 is available for preorder and costs about $360.
