However, even the WSJ has concerns about the price.
Amazon.com Inc. introduced a larger--and more expensive--Kindle electronic reader, and announced deals with major textbook and newspaper publishers as well as universities to expand the market for the device.
The new Kindle DX, which Amazon Chief Executive Jeff Bezos unveiled Wednesday at an event in New York, will cost $489 and begin shipping this summer.
At the $489 price point, it's unclear how much college students and other consumers will embrace the new Kindle. Amazon doesn't release Kindle sales figures, but Citigroup has estimated the current Kindle, which costs $359, will sell roughly one million units this year.
