Strongly disagree. People who can/will happily spend $1800 on early VR correlate very very strongly with people who would spend $2800.
People who aren’t willing to spend more than $400 or $200 or the like however, haha, no.
Seems like “headsets are natural but treadmills are weird” is a self-contradictory/pick-and-choose argument to me. Plenty of gym treadmills feel natural (plenty don’t, too).
No reason it couldn’t do that, but it would need to be big for true prone - rest is easy.
Price, size and durability though… that’s a huge problem.
