> The "disruption" was aesthetics, marketing and ease-of-use

The iPhone (and smartphones in general) have disrupted multiple markets: * Photography and video * Portable music players * Email and messaging devices * Phones ... and many others

The thought I ran into many times with many people during this "disruption" period basically went along the lines of:

"I could buy a new camera, a video camera, a new iPod, a netbook, GPS device, etc - or I could just get an iPhone."
