Hedge fund manager William Ackerman owns a 30 percent stake in Borders — but he doesn't want to anymore. The founder of Pershing Square Capital Management told reporters he thinks Amazon.com should purchase the bricks-and-mortar bookstore: "Amazon could buy the company for about $400 million to get those locations that would take more than $1.0bn to build." Not going to happen. Amazon just let Borders go as an online Web partner without much of a fight. (Photo by AP/Sancya)
