A lot of those prototypes seem to cater to common complaints from first-time or casual VR users - eye strain, focus, fatigue, and weight. I think iterating on these aspects of comfort is important for VR adoption.
Personally, I don't really want or look forward to a future where people spend a lot of time in a headset, but if there were a lightweight, comfortable option it would be fun to explore experiences every once in awhile.
Those improvements are important for enthusiasts as well since they all take their toll during long sessions.
I look forward to having more amazing experiences at my finger tips during the long, dark winter months. There’s not much else to do here except drink and go snowmobiling.
