There's a market for having a plug-and-play videophone now that we have the software to go inside it.
What are Zoom, Facebook or Apple waiting for?
This is already a thing?
Facebook has Portal, Apple has iPad, Amazon has Echo, all of whom support Zoom and other video conferencing apps. The portal even has a moving camera to keep you centered if you're moving in frame, and the iPad does the same thing with an ultra-wide lens and some post-processing.
As far as dedicated videoconferencing hardware is concerned, Starline seems pretty late to the game. Although, I'll admit the fancy 3D imaging features is pretty insane.
