I don't see the big difference from my dad running around with a camcorder when I was a kid (and it was considered normal for families to have really embarrassing home videos watched for laughs, I think AFV made me value privacy), or a modern father using a phone to film, other than with the headset he'd have to look in my direction instead of through an eyepiece or a screen.
I wouldn't be surprised if this year's iPhones include 3D photo / video capture hardware, now that they can talk publicly about the headset. I doubt many people will ever wear one of these to a birthday party, but I could see people flipping a toggle on their phone to capture in 3D. It would take up a bit more storage space, but you could go through and convert to 2D after the fact if you're low on space.
While I can see this as useful for work, every other application does honestly frighten me. We're human. We're embodied. Digital things can be fun, but we're meant to be in the real world.
