Just make sure to post the "IT'S OUT NOW! START DOWNLOADING NOW!" article half an hour before it's actually released, as always. It would feel weird if you didn't.

Universal control is really, really great!

Edit: I've tested it on a my (not primary) MacBook Pro 13" and my M1 iPP 11".
It's really smooth, seamless and "it just works"

I’ve been looking forward to this. Mainly for the FaceID-while-wearing-a-mask option on my iPhone.
