Apple shareholders would like to know what succession plans are in place if CEO Steve Jobs were to quit but, despite an absence of any communication from the company, they're not worried enough to shed their shares.

At yesterday's shareholders' meeting at the Apple headquarters in Cupertino, California the subject of succession planning came up and shareholders asked directors to share their intentions about who could be the next CEO.
However, the company declined to do any such thing, saying it would be against its policy, which leans to protecting business plans and competitiveness.
Shareholders didn't seem unduly fazed, however, and Apple's share price rose slightly – possibly on the news that a new product announcement is scheduled for next week.
It's widely speculated that the new launch will be the iPad 2, geared to the business rather than consumer environment.
