Tim Cook became CEO of Apple one year ago yesterday, following the retirement of Steve Jobs. A soft-spoken, measured, methodical gentleman from the South, he'd been Apple's COO for years, and ran the company on several occasions during Steve Jobs' medical leaves of absence. A logistical and supply-chain genius, he took Apple from being better if more expensive, to much better at prices the competition couldn't begin to match. He helped take Apple from a computer company with a small if premium market share to a consumer electronic juggernaut that could launch products across the world at an unbelievable pace.
