Jeff Bezos, the CEO of Amazon. com, Wednesday introduced Kindle DX - a bigger and advanced version of its popular electronic reader Kindle - which has been especially designed for newspapers, textbooks, and personal documents.

With its nearly 10-inch screen, compared to the present Kindle's 6-inch one, Kindle DX can display PDF documents and hold 3,500 books, as against the 1,500 books for the present model. The $489-priced new Kindle, the shipments of which will arrive this summer, can be used in two modes - landscape and portrait.

Unveiling Kindle DX at a New York event, Bezos said that, Amazon's new move was aimed at establishing the company as the market-leader in the field of electronic books and newspapers - more so as new entrants, like Polymer Vision and Plastic Logic, are venturing into digital reader market.

Analyst Sarah Rotman Epps, of Forrester Research in Cambridge, Massachusetts, said: "Amazon is rushing to get this out to shore up its position as a market leader. In the next year, there will be multiple devices like this that will also have bigger screens and will be able to support newspapers.

The Kindle DX will be made available at a discounted price for subscribers of some newspapers - like The Boston Globe, The New York Times, and The Washington Post - who live in "areas without home delivery."
