Cool!PSVR teardown by SIE
https://www.wired.com/2016/10/psvr-teardown-video/
The most important thing I wanted to see from a teardown was the lens profile (which supposedly acheived an oval exit-pupil?)
but noooo..... "The lenses are glued to the barrel so they cannot be disassembled"
Hopefully ifixit will find a way... they always find a way.
