Let the hive mind of Engadget get that for you.
"We need a digital camera that can be switched on and fire off that first shot fast. It's not a commonly tracked statistic on any review site, and nobody seems to have this information for every camera. We were hoping other readers could inform us as to what small digital cameras can fire off their first pics in under a second (ideally under half a second). It needs to be small, but mostly, just really quick in operation. Thanks!"
Oh for crying out loud! Johnny 5 didn't had any skin and people reacted (mostly) good towards it. Nobody seems to be scared when watching C3PO naked. This is one of those "Why, oh, why would they do that" studies, mostly because we all know how the Terminators are going to look like.
By the way, we react like that because of the primordial instincts, being that if you happen to encounter a decaying corpse it is most likely to have lots of diseases and bacteria and such that, albeit with time, could render you dead as well. So as a mechanism of protection, we tend to at least step back (unless you are desensibilitized, e.g. by watching such great movies as Cannibal Holocaust while eating breakfast).
