Have you ever tried Moto Active Display ?
I am perfectly chilled. Myself and Epicryban were having discussion after the video posted about the differences between them and someone else butts in and starts to get a bit ratty and aggressively defensive because of the suggestion Moto does this display feature better.
The point also is that with Moto display you may get a message or email or multiples of both and you can see what they are and decide if you need to wake your device or not. Whereas with Google and Samsung & LG's version - you wake the device to even check what they are. You can't swipe between them like on Moto display, you can't change music or of using chromecast control video and such like you can on Moto display, all whilst keeping the screen in a low power state.
That's the whole point of the technology, to keep the screen off for trivial things, whereas the other implementations all rely on you waking the device fully, and moreover LG & Samsung unlock and turn on the device fully to see who those missed calls and other things were from - thereby undermining the point of an ambient display.
Moto must clearly have patents on their form of interactivity as even Google when they owned Moto haven't copied its implementation, and we can only assume that Patent now belongs to Lenovo.
But regardless as this form of always on / low power notification technology, currently Moto provide the better solution than all the others.
