The "Super Retina" display is 5.8 inches, with a 2436 x 1125 resolution -- that works out to 458 pixels per inch, by far the highest ever seen on an iPhone. Phil Schiller also notes that it's an OLED screen, the first that's "good enough" for an iPhone. The screen supports HDR, and naturally includes 3D Touch technology and the "True Tone" display found on the iPhone 8 and iPad Pro.

To accommodate this giant display, Apple has ditched the home button and Touch ID. You can raise the phone to wake it up, but you can also tap the screen to do the same. Given that every iPhone has had a home button, this change might even be a bigger deal than the bigger screen. To get home, Apple has added gestures like the ones we've seen on the iPad for years — a swipe up from the bottom gets you back to the home screen, while swiping up and pausing will bring you to the multitasking menu. To access Siri, you can say "Hey Siri" or hold the side button, which Apple has enlarged. The phone is wrapped with stainless steel and has glass on the front and back; surprisingly, it comes in only two finishes: silver and black.

To replace Touch ID, the iPhone X is locked until you look at it and it recognizes you. Apple is calling this "Face ID." It uses the front-facing camera as well as other sensors, including an infrared sensor, flood illuminator and dot projector, to unlock the phone. (Apple refers to it as a True Depth sensor.) It'll update your face scan frequently to account for changes like haircuts, hats and beards. Schiller says it's a one-in-a-million chance that someone else's face would unlock your phone, as compared with one in 50,000 for Touch ID.

Face ID will also let you authenticate Apple Pay purchases -- by clicking the side button twice and looking at the screen, your phone will make the desired payment. And Apple's also using the True Depth sensors to let you create and share animated emojis. The company is starting with a dozen different emojis (most of them animals) that you can animate using your face.

As for the camera, it's a dual camera, much like that on the iPhone 8 -- it has dual 12-megapixel sensors with a f/1.8 aperture on the wide end and f/2.4 on the telephoto lens. The big thing to note here is that both lenses have optical image stabilization, while the iPhone 8 Plus has only OIS on the wide-angle lens. It also features factory calibration on the cameras, for augmented reality, as well as the new software-enhanced "Portrait Lighting" mode found in the iPhone 8 Plus.

The processor is the same as the A11 Bionic chip found in the new iPhone 8, and it sounds like a big step up over last year's processor. It's a six-core CPU, with two high-performance cores. Those high-performance cores are 25 percent faster than the A10's, while the four high-efficiency cores are 70 percent faster than the A10's. Apple also designed the GPU for the first time and says that it's optimized for the company's Metal 2 graphics framework.
