27. Paul S. Otellini
President and CEO, Intel

Otellini is the first non-engineer to lead Intel, which maintained its dominance over the $30 billion computer microprocessor market this year.

Otellini's biggest challenge: The explosive growth of the tablet market, where Intel has struggled to compete against upstart chipmaker ARM.
