The other poster is also right about resolution issues. To get any decent amount of text on the screen, you'll cause a lot of eye strain.
Waiting for my Piimax 8K-X to see what the greater and field of view and nominally better pixel density does for it.
If this is what I think it is, it is going to be huge. The buzz is that someone has discovered a cure for motion sickness, and it's incredibly simple: just wear a small vibrating device on the back of your head, sending a continuous vibration signal to your inner ear. For reasons unknown this seems to deactivate whatever part of the vestibular system is responsible for motion sickness. It is supposedly effective in >99% of people and does not disrupt balance.
Read the inventor's description here: https://www.reddit.com/r/oculus/comments/9ywify/inventor_may... Of course a cure for motion sickness will be great for VR but the applications in everyday life will be much, much bigger.
You don't tend to get it with room-scale setups.
I'm hopeful that decent inside-out tracking will be a thing in 2019 - then it's off to the races.
Perfect inside-out tracking with hand tracking, mixed VR and AR - that's when consumer VR gets big.
Even if the headset tracks in 6-DoF most games still need some form of artificial locomotion. Rarely is it acceptable for the entire game to take place in the same 5ft x 5ft space, and introducing artificial movement causes motion sickness for some people. Just letting users teleport doesn't always cut it.
Hopefully, things like VR and the need for a better understanding of vestibular disorders will drive funding and understanding[1].

One is indeed reducing emissions from the device.
The other is reducing the emissions from the environment which might affect high speed or otherwise sensitive circuits.
The shields themselves weigh very little, and there is a risk that you'll damage the board trying to remove them too.
(Note that humans have 210 degrees FOV, and from the looks of those goggles, it seems to be a lot less, but I could be wrong)
