Image Gallery: E-Book Readers

Electronic book readers are closely related to multi-touch tablet PCs in design, and to a lesser degree in function. Amazon's Kindle dominates the market, but competition is blazing.

The Kindle DX, which sports a 9.7-inch diagonal, black-and-white screen, is Amazon's largest e-book reader. Screen resolution is 1200 x 824 pixels. The addition of global wireless, makes it possible for people in more than 100 countries to download electronic books, newspapers and magazines. The DX costs $489.
