Almost exactly two years after he took his first medical leave of absence, Apple CEO Steve Jobs is taking another leave of absence to "focus on [his] health." Apple COO Tim Cook will take over day-to-day operations while Jobs will remain as CEO. Here's his email to all Apple employees:

Team,
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.
Steve

On behalf of everyone here at TiPb and Smartphone Experts we wish Steve Jobs a full and fast recovery.
