Steve Jobs was in Apple offices for a complete work day on the day of his resignation as CEO, according to a person described as "close" to the executive. Jobs is in fact said to have attended a regular board meeting, in spite of being in a "weak" condition and having been housebound for several weeks. The resignation is not a sign of a sudden plummet in Jobs' health, the anonymous source claims. A separate source alleges that Jobs had an emotional meeting with his executive staff after talking to the board, whom me told he intends to be an active chairman.
