When Steve Jobs took the stage at Apple's Worldwide Developer's Conference today, the audience response made one live blogger question if he was at a Beyoncé concert.

In his opening remarks, Jobs mentioned that the event had sold out in two hours, and apologized to those who failed to secure one of the 5,200 tickets.

Not much later, the top tweet on Twitter was Steve Jobs is Oprah Winfrey for Men, referring to both Jobs' heroic status and the fact the iCloud is being offered for free.

Until today, most believed that iCloud would have a $25 pricetag, but today, Jobs announced that it would be free of charge (and free of ads).

iCloud is essentially a 'floating' hard drive that stores a user's content, which can be accessed wirelessly from all their devices. Users will be able to perform multiple downloads to up to nine iCloud-enabled gadgets without incurring any added costs.

The Apple CEO's keynote speech was breathlessly anticipated, due in large part to the fact that Jobs has been on medical leave from Apple since January, and out of view with the exception of an appearance at the iPad 2 launch in March. Apple enthusiasts were just as eager to observe Jobs' condition as they were to learn about iCloud and Mac OS X Lion, Apple's upcoming desktop operating system.

Jobs was diagnosed with pancreatic cancer in 2003 and had a liver transplant in 2009.

His authorized biography, iSteve: The Book of Jobs, is already a top Amazon bestseller even though it will not be released until March 2012.
