Apple CEO Steve Jobs came back from medical leave on Wednesday to unveil his company's new and updated iPad.
"We've been working on this product for a while and I just didn't want to miss today," ABC News and other outlets quoted Jobs as telling the crowd at Apple's event in San Francisco.
Jobs, who has become increasingly thin since he was first treated for a rare form of pancreatic cancer in 2004, took indefinite medical leave in January.
He has given the public few details about his illness, to the fury of many investors, who link his health with the health of the company.
The new iPad is thinner than the first generation model, has two cameras for taking photos and video chatting, and a faster processor. Apple said it would become available in the U.S. March 11 and elsewhere by March 25.
Apple sold nearly 15 million iPads in 2010. Analysts have predicted the company will sell 30 million of the devices in 2011.
Chief operating officer Tim Cook has been in charge of Apple's day-to-day operations but it is not clear what plans Jobs has for the long-term.
The type of pancreatic tumor he had, called a neuroendocrine tumor, is more treatable than other forms of pancreatic cancer, but Jobs' continued weight loss and repeated medical leaves have worried investors.
