NEW YORK -- Steve Jobs is the public face of Apple, but that doesn't mean investors get to know every last detail about the CEO's health.
Jobs announced this week he is taking his third medical leave from the company he started in 1976.
No date was given for when he will return. No information was provided about what was wrong. No interim CEO was named, though Chief Operating Officer Tim Cook will be responsible for Apple Inc.'s day-to-day operations.
