The signature new feature on the iPhone X is its face recognition, which powers its FaceID authentication system. But that's not necessarily its biggest selling point. While Apple's FaceID is leaps above any other face recognition technology on the market, it's replacing fingerprint recognition on other recent iPhones that also works quickly and consistently.
Between the lines: The real advantage of the iPhone X is you get a bigger screen and dual cameras in a smaller phone. And it's on that front where the iPhone X really earns its money. It delivers more screen real estate for Web browsing, e-mails and movie watching, plus the benefits of a second camera, all in a device that fits comfortably in the hand.
