Amazon Kindle compare (global wireless, 2009 version)

The third-generation Kindle's winning combination of noteworthy upgrades--an improved screen, better battery life, lighter weight, and lower price--vaults it to the top of the e-book reader category.

While Sony Reader Pocket Edition PRS-300 has a basic feature set, its $200 price tag, compact size, and Epub file compatibility make it an appealing e-book reader.

While the new internationalized Kindle looks exactly like the earlier U.S.-only model, this e-reader, which uses AT&T's data network for wireless access, represents an incremental improvement to the Kindle line--just as serious competition is ramping up in the e-book market.

Although it has all the positive attributes typically associated with a Kindle device, the arrival of Apple's iPad seriously affects the Kindle DX's viability unless Amazon lowers its price by at least $100.
