Earlier quoted context omitted.
Everyone is missing maybe the biggest point - this isn't just a VR device. You can run some/many (depending on your library) of your regular Steam games on a 'flat screen' inside the VR environment, which makes this much more like a SteamDeck with a giant private screen for a lot of people.
You can do this really well on $200 AR headsets that fit on your face like sunglasses and uses the battery of the device it's plugged into to last many hours. If this is the biggest point, then I don't see why Xreal isn't more popular.
As the form factor is already pretty bulky, keeping it as a single device helps a lot IMHO.
