The Story HD is the first dedicated e-reader to integrate Google's eBookstore, using a built-in Wi-Fi connection to download digital books. It launches for $140.

Until now, the Google eBookstore has been available through the Web and through apps for Android and iOS. E-Readers that support , such as Barnes & Noble's Nook and Sony's Reader, can load Google eBooks from a PC, but they can't download them directly onto the device. The launch of a dedicated eBooks reader puts Google's store more directly in opposition to the Nook and Amazon's Kindle.

iRiver, meanwhile, hopes to differentiate its e-reader with a 6-inch, 768-by-1024 resolution display, which according to the company provides 63.8 percent more pixels than the competition. The Story HD also includes a QWERTY keyboard, three weeks of battery life, and support for both and PDF formats.

But there's no shortage of stiff competition in the dedicated e-reader market. and both recently launched touch screen e-readers for $139 and $130, respectively, and Amazon has found success with its $114 . The ad-subsidized e-reader, which sells for $25 less than its Kindle counterparts, is on Amazon's Website. (Surprisingly, Google isn't using its own ad prowess to subsidize the Story HD.) And although Google prides its bookstore on , its e-reader rivals are doing exactly the same thing.
