Steve Jobs has made it to the event at Apple's Cupertino, Calif., headquarters, and recieved a standing ovation.

Speculation was rife that Jobs would attend, despite skipping many other Apple events, including the company's annual shareholders' meeting, since he went on medical leave in January.

The tech world is waiting with bated breath to know what features will be added to Apple iPad, which changed forever the dynamics of the computing business.

The only major event Jobs attended since the start of his medical leave in January was a dinner with President Barack Obama, at which he met technology industry leaders.

Though Jobs took a new medical leave in January and handed over the company's daily operations to chief operating officer Tim Cook, he never completely disappeared from the scene. There were reports last month that Jobs was deeply involved in a project to launch a cheaper version of the iPhone, and he was seen on the Apple campus.

Rumor mills went into overdrive last month after the U.S. tabloid National Enquirer published an article which said Jobs was close to death. The tabloid quoted doctors as saying that Jobs had roughly six weeks left.
