Amazon.com cut its Kindle price by $70 to $190, and Barnes & Noble did likewise with the Nook. This is no doubt to fend off Apple's fast-selling iPad, but should also keep people buying those high-margin $15 e-books. Clever.

Barnes & Noble is making an e-reader; Gizmodo published the first pictures today. With similar media-tech fusions out or anticipated from Amazon.com, Apple, Hearst, Time Inc. and others, it's tough to keep track. No worries; here's a list.

Silly Barnes & Noble plans to take on Amazon's Kindle by releasing its own e-reader.

Longtime Amazon.com partner Borders opened an independent storefront on the Web today. Analysts don't hold high expectations for the new Amazon rival and Borders Group Inc. president and CEO George Jones told the AP the company knows what's up its up against. "It's not the intent that we're going to out-Amazon Amazon at what they do," Jones said. So what is the intent behind Borders's store on the Web? Likely, Borders opened shop on the Web to help sell the company. Two months ago, Borders announced it was for sale and only last week, Barnes & Noble confirmed a team of its executives are looking into a deal.
