Apple chief executive Steve Jobs is stepping aside for a few months to focus on his health. Tim Cook will look after operations in the interim.

In a letter to Apple employees, Jobs writes: "I am sure all of you saw my letter last week sharing something very personal with the Apple community.
"Unfortunately, the curiosity over my personal health continues to be a distraction not only for me and my family, but everyone else at Apple as well. In addition, during the past week I have learned that my health-related issues are more complex than I originally thought.
"In order to take myself out of the limelight and focus on my health, and to allow everyone at Apple to focus on delivering extraordinary products, I have decided to take a medical leave of absence until the end of June.
"I have asked Tim Cook to be responsible for Apple’s day to day operations, and I know he and the rest of the executive management team will do a great job. As CEO, I plan to remain involved in major strategic decisions while I am out. Our board of directors fully supports this plan."
The move comes just days after Jobs declined to make his traditional keynote address at Macworld, which once again raised concerns about his health.
He has been steadily losing weight over the past months, and recently confided that he suffers from a hormone imbalance which is now being treated.
