I was at the keynote when Steve Jobs launched the iPhone in 2007. It was an amazing introduction—historic for Apple and the consumer electronics industry. One thing that everyone was asking for after the launch was apps. On July 10, 2008, Apple launched the App Store, forever changing the way we use smartphones, tablets and many other devices. Think about how you used devices before apps, and how you use them today—there is no comparison. The iPhone and apps have changed the world.
