In no particular order:

- 4K Apple TV (with HDR support, and a bunch of games, so Apple is going after the game console market, I guess)

- 3rd generation Apple watch, now with optional cellular (and it can receive calls with "the same number as your iPhone", which sounds like an interesting trick with call forwarding)

iPhone 8 / 8 Plus:
- six cores (2 fast, 4 slow), 4 billion transistors (!)
- glass on both sides, custom aluminum alloy
- color calibrated, HDR display
- 12MP camera, supposedly lower noise, etc., as well as 4K/60Hz or 1080p/240Hz slow-motion
- separate camera(s) for augmented reality (stereo vision, etc.) on the "Plus" model
- wireless charging (using the Qi standard, not something proprietary!) -- curious because all the Android vendors seem to have abandoned this

iPhone X:
- full edge-to-edge front screen (like the Essential phone)
- high res screen, but not even close to the highest Android devices
- dual 12MP cameras, with different apertures (same as the iPhone 8 Plus, not sure about the iPhone 8)
- supposedly more accurate colors than "traditional OLEDs" -- sounds like they just ran a color calibrator
- no more home button (just like Android!), now they use face recognition (as Android once did, but was considered insecure, easily spoofed with photographs, supposedly better now that they've got multiple front-facing cameras so they can sense depth, plus an IR emitter/receiver combo)
- and a custom "neural" co-processor for machine learning stuff

The security story here, versus fingerprint sensors, is a bit odd. They're throwing a huge amount of horsepower and technology at a problem where the modern Android solution (bigger fingerprint sensor on the back) seems simpler and more reliable. Apparently the real driving force here is being able to do face tracking, and thus map your face onto a character in virtual / augmented reality.

The value premium for the edge-to-edge screen seems dicey. When you see people with iPhones, they always, always have them in some sort of case. Those cases cover the unused parts of the bezel. To put an iPhone X in a case, the case will have to be that much bigger, since it has less of the phone to hang onto.
