There's no room for revolution in smartphone space anymore. The market is too competitive and everybody is tracking it too closely. Revolution can take place in overlooked product categories

What about in overlooked user interface technologies? I think FaceID would be great for unlocking the a MacBook laptop. Also, the face that Apple can now get ahold of those sensors for cheap and at scale probably opens up the opportunity for user interface innovation. People like to use touch for certain operations on current laptops with a touch screen, but some of those might be better done with a gesture away from the screen the doesn't cover up the view of the screen. (Or require the user to lift their hands up from the palm rest to avoid gorilla arm.)

Tablets existed before multitouch and the first iPad. It was a thinner form factor enabled by better battery and more frugal processors combined with multitouch which made the iPad what it is.

This is in absolutely no way revolutionary. Not least because some Windows laptops have been able to do it for some time (HP? I forget who did it, but it was awful)

I'm not sure that "been able to do it for some time, but it is awful" counts as being able to do it. Imagine if your MacBook recognized faces correctly 100% of the time, and would automatically login to your account, your wife's account, or your kid's limited accounts depending on who it was that opened the lid. I don't know if that's revolutionary, but it sure would be easy to use.

You can do this already for a few years now. Surface Pro 4, Surface book, Surface Laptop all have it. Works flawlessly.
