It's a prototype for crying out loud. It's not meant to be a consumer device and it's not being advertised as one. Get off your high horse mate.
I feel like the looking ridiculous factor is a perfectly reasonable fear to have and a big reason why I wouldn't buy it. Downvote away but it's a reasonable stance to take IMO and this clearly suffers from it more than VR.
Besides, while it is a fair point to make, people using cell phones looked ridiculous back in the days. And yet everyone has a cell phone now. I don't think the ridiculous-factor will be a major blocker if the benefits of the device outbalance it.
