I can't imagine most people will want to wear that headset for more than the 2 hours the battery lasts. I know I haven't when wearing existing vr headsets. I seem to max out at about 30 minutes.

I think to get to a consumer version Apple will want to drop all of the glass and metal and go for lighter plastic instead. They need to drop the secondary outward facing screen as well for weight, battery and cost savings.

If things can get comparable to thicker framed normal glasses, that will be when VR/AR can really become mainstream.
