Hahaha ...
The only reason I knew, is our most recent two trips to Universal Studios the end of last year, they were _everywhere_. I keep seeing these long sticks with what appeared to be cameras popping up from the sea of people. Most of these appeared to have a tiny camera (vs. a phone) mounted, assuming it's sold all together (and camera electronics are so cheap now).
Do we take pics? Sure. We get out of the way, don't suddenly stop in a high traffic area, use an iPhone, quickly shoot (talking < 5 seconds) and we're off.
While I'm on it, you folks with the nice P&S cameras, that should be able to go from off to a nicely framed, instantly focused shot ... WHY do you take so long to shoot a photo? Learn to use the camera _before_ you're in a position to want to use it.
