You say that now, but bulky embarrassing camcorders at kids birthdays were a major thing in their day. Perhaps there will be some livestream type features to share the birthday with grandparents across the country in 3D.

Yep. Mine were filmed with one of these. But dad would film for a few minutes, put it down, smile and wave, hand it to mom.

Having something strapped to your face is a different beast.

I dare say one of the next iphones will introduce the 3d video/photo capture capability. Then you could capture with the phone and view it later on the headset.
