Steve Jobs has decided to take a medical leave regarding new concerns about his health. Two years ago he also took a medical leave for six months to undergo a liver transplant. He also took a medical leave in 2004. Jobs recently sent a memo to staff that states:

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

As of now, Apple COO Tim Cook will be filling in for Jobs during his medical leave. Hopefully he'll be back soon. Feel better, Steve!
