There was mention of a DisplayPort, so is there a way to just stream your MacBook into it?
Closing the lid and working in one of these would be great, but there's always a caveat that blocks this.
The Quest series supports both wired and wireless streaming, so I'd be surprised if that wasn't an option.
You can, but the FOV is narrow so not great for multiple screens, and the focal length is probably around 4 ft so you're not going to be able to use a screen closer without eye strain.
