There are third party wireless streaming devices that function with the Index. It doesn't take much compute to operate wifi and process minimally compressed video.
A headset with Chromebook equivalent hardware would be significantly cheaper than a headset with Steam Deck equivalent hardware.
They wanted a device like the Quest that would let people play decent VR without needing a strong PC. I think that was the right decision when it was being planned. But now that we're mid-RAM apocalypse, the better move may have been to iterate on the Index and not try to make a new platform.
