We know the iPhone as the device that transformed our world, changing everything from how we talk to each other and do business, to how we exercise, travel, shop, and watch TV. But packed within its slim profile is the fascinating, untold story of scientific, technological, and business breakthroughs--global in scope, sometimes centuries in the making, and coming from vastly different disciplines--that enabled Apple to create the most profitable product in history.

For all the time we spend swiping, tapping, and staring at iPhones, you think there would be few things we didn't know about these gadgets. But think again.

As multifaceted as the invention it follows, The One Device is a roving, wide-lens approach to tech history that engages the imagination as it explores the marvel of engineering that millions of us use each day.
