The device that started the smartphone revolution/Everyday Objects
When Steve Jobs unveiled the original iPhone in January 2007, it had no App Store, no copy-paste, no 3G, and no front-facing camera. What it did have was a multi-touch screen and the audacity to charge $499 for a phone. It sold 6.1 million units and permanently rearranged the tech industry. By modern standards it is a charming paperweight with a 2-megapixel camera.
