It is vastly underpriced for the hardware it gives. Some is paid upfront and the rest is paid in data collection etc from facebook.
They have a "unconnected" version for sale for 800 USD and a service fee of 180 bucks. You can see how much you have not paid for in those prices when you go with the ad version.
If the Quest 2 was not associated with facebook I would have owned one a long time ago.
