"The move pits Amazon.com, based in Seattle, against a range of other players in the growing global market for digital reading. The rivals include iRex, a division of Royal Philips Electronics, the Dutch consumer electronics company; Sony; and China Mobile, the world's largest mobile carrier, which said last month it would soon begin selling several kinds of electronic reading devices."The new Kindle is physically identical to Amazon's current Kindle, with its slender profile, six-inch black-and-gray screen and angular keyboard.

Sprint's network is incompatible with most mobile networks outside of North America."
