One could easily describe the design of Apple's iPhone as iconic. If you asked someone to draw you an iPhone, even a child, they would draw a rectangle with rounded corners, with a rectangle on it for the screen, and a small circle underneath the screen for the Home button.

But this year, Apple is resolving to change all of that, as the iPhone X features a radical redesign. The Home button is gone in favor of stretching the screen across the device, and the aspect ratio has changed.

This also means that the entire user experience has changed, as the Home button has been replaced by swipe gestures and facial recognition. But Touch ID was so good; can Face ID really measure up? Can users really be trained to use their iPhones in an entirely new way when they've been using it one way for ten years?
