Via El Reg comes news that Carl Icahn has, after a brief battle with Michael Dell for control over the company, thrown in the towel. From the article: "Icahn said in an open letter to shareholders that he still thought that Big Mike's $13.88 per share offer for the firm undervalued it, but had decided that it would be 'almost impossible' to win the battle at the shareholder vote on Thursday. 'I realize that some stockholders will be disappointed that we do not fight on,' he wrote. 'However, over the last decade, mainly through "activism," we have enhanced stockholder value in many companies by billions of dollars. We did not accomplish this by waging battles that we thought we would lose.'"
