Meta's lineup isn't a fair comparison IMO, since those include significant compute power to a actually run the software, battery, inside out tracking, and are completely untethered, all for about half of what this costs. This is a tethered display that relies on separate controllers, lighthouses, and computation.
That said, lightweight is awesome. I think getting weight out of the headset is going to be really important for any sort of casual use of VR, but I don't think this product is good example of that, just because of all the other requirements.
