5. Sam Palmisano, IBM

Rometty's appointment at IBM, of course, means the passing of the torch from another IBM legend: Sam Palmisano, whose last day as CEO of Big Blue was Dec. 31, though he'll continue as chairman. Palmisano, who became CEO in 2002, presided over one of IBM's biggest-ever strategic moves: its decision to sell off its PC division, in 2004, to China-based Lenovo and also set IBM on a course defined by software and services, and less on hardware sales.
