Apple CEO Steve Jobs appeared on stage to standing ovation Monday, where he was expected to announce a new service called iCloud.
Jobs, on a break from a medical leave he started in January, looked thin as he came out in his signature outfit of mock turtleneck and blue jeans. One audience member shouted out, "we love you."
James Brown's "I Feel Good" played over the loudspeakers just before he appeared.
Apple Inc. released few other details before Monday's event. He made a public appearance in March to announce a new iPad.
ICloud will apparently allow customers to store their music online. The company has been in talks with the major recording companies to make this possible.
ICloud could give users a wide array of music for their iPhones, iPads and Wi-Fi-capable iPods, without having to connect them to their home PCs to transfer songs. Google Inc. and Amazon.com Inc. have launched similar services.
