Perhaps most integral to Jobs's legend was unbridled chutzpah and cojones. He routinely matched his peerless visions with bold and often controversial leadership. At his core, Jobs was a fearless and tireless iconoclast with no patience for outmoded ways of thinking. This is perhaps most evident in a string of well-studied incidents that includes the elimination of the floppy disk with the original iMac; his initial insistence on a uniform 99 cent price tag for songs sold in iTunes; and in the critical blows dealt to Compact Disks and Flash animation with the MacBook Air and iOS devices respectively. And that's to say nothing of a risky foray into mobile products, from the iPod to the iPad, that eventually changed the core identity of the company formerly known as Apple Computer.

Jobs famously eschewed the market testing that drives development at most companies, insisting that the customer doesn't know what they want until you show it to them. That sort of thinking would land most CEOs in the poor house, but somehow Jobs always seemed to know the right thing to do.

Apple will likely have many more CEOs over a long life as a highly lucrative and influential company, but it will never replace Steve Jobs. He was one of a kind.
