An anonymous reader writes with this excerpt from Network World: "A number of sites are reporting that Apple's CEO Steve Jobs is taking a leave of absence till June at least. Speculation over Jobs' possibly failing health has run rampant in the past few weeks. Prior to the recent MacWorld show, Jobs said he had a hormone deficiency that had caused him to dramatically lose weight. In a memo today Jobs told workers his health issues are more complex than he thought."
adds a link to this letter from Steve Jobs
on Apple's website, which also says that Tim Cook will be responsible for daily operations, though Jobs will remain involved with major strategic decisions.
