At the WWDC Keynote, Steve Jobs unveiled the many great features of the newly released OS X Lion. The Keynote continued to highlight the sale of more than than 200 million IOS devices. ”That makes iOS the number one mobile operating system, with more than 44% of the market.”

To talk more about the IOS 5, Scott Forstall enters the stage. In reference to the iPad 2, Scott Forstall says, ”It is an amazing product, and our customers just couldn’t wait to get their hands on it… actually they did have to wait.”

“More than 15 billion songs have been sold through the iTunes Music Store, making it the #1 retailer of music in the world.”

Forstall also explains that Apple has paid out more than $2.5 billion to developers — big check signed by Steve Jobs on the screen.

Now, getting to the IOS 5, ”iOS 5 is a major release. This is incredible for our developers and our customers.”

The first new feature discussed is Notifications. We’re looking at the current notifications, the annoying pop-ups that have been “massively popular.” More than 100 billion have been pushed so far!
