The new DX model sports a new graphite enclosure, it's about a third of an inch thick and can carry 3,500 books. And speaking of books, Amazon's Kindle Store now offers over 620,000 titles, most priced at $9.99. The storefront added more than 200,000 books in the last six months, and also features over 1.8 million free out-of-copyright releases.
The updated Kindle DX model arrives just a week after Amazon slashed the price of its original Kindle unit from $259 to $189. The company believes its devices' non-glossy, paper-like screens are much better suited for reading books. But despite recent moves to price hardware more aggressively, the company is in the business of selling e-books, and is fine with users reading them on whatever's available. So far, they've released apps for the iPhone, iPad, and Android devices.
