Steve Jobs took to the stage at an Apple event in San Francisco Wednesday, marking his first major appearance since a five-month medical leave this year. Jobs opened up by acknowledging the generosity of the organ donor who gave him the new liver that saved his life. The New York Times blogged that he "looks well, though as thin as when he left the company in January." Jobs then went on to tout the latest improvements to the iPhone and iTunes, and also unveiled a new music format called iTunes LP that is meant, according to Jobs, to "get people to buy music albums again." Google's CEO, Eric Schmidt, was also spotted at the event.
