Jobs sent a note Monday, Jan. 17, 2011 to employees saying he's taking a medical leave of absence so he can focus on his health. He says he will continue as CEO and be involved in major decisions but has asked Tim Cook to be responsible for all day-to-day operations. Jobs was a liver transplant recipient in 2009.
