While it's ignited plenty of debate, there's no question the iPhone X represents a milestone in Apple history. At 5.8 inches, the iPhone X has the largest display ever on an iPhone, and also features the first "edge-to-edge" iPhone design (aside from the camera notch at the top). Additionally, the display switches to OLED technology for improved colors and contrast. The iPhone X also removes the home button and TouchID fingerprint recognition, instead introducing FaceID facial recognition technology for unlocking the device. Meanwhile, like the iPhone 8, the iPhone X comes with wireless charging and improved augmented-reality capabilities, as well as a dual-camera setup and the speedy A11 Bionic processor.
