He was back at work on schedule in late June, though the company said he would work from home part of the time. In January 2010 he appeared on stage in San Francisco to announce the iPad, and was in the spotlight again in September to launch a new version of Apple TV.
In January 2011, Jobs said he would be taking another medical leave of absence, not saying this time how long he would be away. But while on leave, he appeared on stage at a San Francisco event in March to introduce the iPad 2 , and in June to introduce the iCloud and iOS 5 at company's Worldwide Developers Conference. By the June event, Jobs, looked gaunt, though he spoke with enthusiasm about the new iPad. Two months later, he stepped aside as CEO, writing to employees: "I have always said if there ever came a day when I could no longer meet my duties and expectations as Apple's CEO, I would be the first to let you know. Unfortunately, that day has come."
Jobs is survived by his wife, Laurene, and four children.
