The continuity camera is pretty amazing. Just the fact that you can have an upgraded camera + center stage to track you and adjust the lighting perfectly. Then that desk view really is something. I'm amazed.
I'm not sure about this feature working on Windows. The only information I could find was https://www.computerworld.com/article/3664335/how-iphone-users-with-windows-pcs-can-get-continuity-camera-features-now.html. It looks like there is an app called Camo that lets you do something similar, but I'm not sure about desk view.
I have a feeling Apple's official feature will be on Macs only, kind of like Airdrop.
