The retail giant Barnes & Noble is taking on Amazon.com by releasing an e-reader of its own. The wireless electronic device will hit stores by the end of November and could challenge the Kindle's dominance of the marketplace. The reader will be called, Nook, and cost $259—the same amount that the Kindle sells for. Unlike the Kindle, Nook users will be able to lend digital books to their friends for up to 14 days.
