Apple CEO Steve Jobs, who has been on indefinite medical leave, is making an appearance as he unveiled a new iPad in San Francisco.
Jobs walked on stage to standing ovation. Jobs looked frail, wearing his signature black mock turtleneck, blue jeans and wire-rimmed glasses.
Apple is unveiling the second generation of its iPad at Wednesday's event. Jobs told the audience, "We've been working on this product for a while and I just didn't want to miss today."
The new device has two cameras for taking photos and video chatting. It has a faster processor. It's also thinner.
It's available March 11 in the U.S., then March 25 in at least 26 other countries, including Mexico, New Zealand and ones in Europe.
