Revealed: Tech titans of the past 25 years

Michael Dell, chairman of the board of directors and chief executive of Dell — the company he founded in 1984 — came in at third place, with 53 percent of voters.

However, 2007 has not been Dell's (the company and the man) best year. In February, the company announced that Kevin Rollins had resigned as chief executive officer, and Dell had retaken the helm of the PC company.

Rollins' departure comes after a terrible year for the company, during which it lost its lead in PC market share to HP and an investigation by the SEC for possible accounting improprieties began. Several executives have left the company in recent months, including chief financial officer Jim Schneider, who was slated to leave the company at the end of January.
