Apple CEO Steve Jobs today sent the following email to all Apple employees:
At my request, the board of directors has granted me a medical leave of absence so I can focus on my health. I will continue as CEO and be involved in major strategic decisions for the company.
I have asked Tim Cook to be responsible for all of Apple's day to day operations. I have great confidence that Tim and the rest of the executive management team will do a terrific job executing the exciting plans we have in place for 2011.
I love Apple so much and hope to be back as soon as I can. In the meantime, my family and I would deeply appreciate respect for our privacy.
The New York Times says:
Mr. Jobs suffers from immune system issues common with people who've received liver transplants and, as a result, his health suffers from frequent "ups and downs," according to a person with knowledge of the situation, who agreed to speak on condition of anonymity. In recent weeks, Mr. Jobs began a down cycle and slowed his activities at Apple, the person said. Mr. Jobs has been coming to the office about two days a week, and appeared increasingly emaciated, the person said. He frequently lunched in his office, rather than in the company cafeteria, the person said.
