A week ago Jobs disclosed in a letter to employees that health issues required him to take a leave of absence until the end of June. The announcement came a little over a week after he revealed that his gaunt appearance lately, which has been the subject of much speculation, had been caused by a hormone imbalance.

When announcing his leave, Jobs declined to reveal further details about his condition except to say that it was more complex than he originally thought. The setback follows surgery he underwent in 2004 for pancreatic cancer.
