Steve Jobs takes stage at Apple's iCloud event

SAN FRANCISCO (Reuters) - Apple Inc CEO Steve Jobs strode back into the spotlight on Monday to unveil the iCloud, a music-streaming service that the company hopes will power its next stage of growth and popularize Web-based consumer services.

Jobs' appearance, usually closely scrutinized by Wall Street, will cheer investors still worried about his health after the pancreatic cancer survivor went on his third medical leave in January for an undisclosed condition.
