Those among us playing around with Pi 2 may pay attention to a small design flaw. If PCB is hit by flash or laser pointer you will blind your device. Sounds funny and it is.
Raspberry Foundation confirmed the findings of a photog: http://www.raspberrypi.org/xenon-death-flash-a-free-physics-lesson/
And smartphones are not bright enough to be of any concern.
An old saying comes to mind: http://en.wikipedia.org/wiki/Wear_Sunscreen
EDIT: Discovering the photo effect earned Einstein the Nobel prize in physics. Onion's findings just earned him a remark in some lame posts. Sic transit gloria mundi!
