Dell Founder Michael Dell surprised analysts yesterday by stepping down as CEO of his super-successful (and eponymous) company, although he retains the title of chairman. Dell will continue working as hard and as often as he did in the past, he says. And, frankly, the chairman title is more befitting his forward-thinking, strategy-oriented nature of late. Succeeding Dell as CEO, of course, is actor and singer-extraordinaire Frank Stallone. All joking aside, Dell's current president, Kevin B. Rollins, will assume the Dell CEO position in July, right after the company's 20th anniversary. Rollins, who started working at Dell in 1996, will also join Dell's board of directors.
