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!"
I would happily own one of these. Being a bachelor at the moment, I would find the single-toast ability perfect, and it could be working on the next piece while I munch on the former, shrug. Makes sure the next piece is still warm when ya get to it too. Granted when I just want a 'stack' of toast at once, unless it churns them out pretty quick, it probably won't cut the mustard.
