John Sculley, 66
When this former Pepsi exec ran Apple from 1983 to 1993, he was known for walking around with his Newton handheld computer. Today he uses a PC (and no, he doesn't own an iPod). A venture capitalist at RHO Capital Partners in New York City, Sculley still focuses on technology innovation. What does he think of Apple's resurgence under Steve Jobs, the man he once fired? "They've made beautiful products, well thought through, with no compromises and great styling," he says. "And they've made a market for them."
