"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!"
Guess I'm going with the Palm Pre then. Same old iPhone GUI is boring me. Only one app open at a time feels outdated and confusing on such as powerful phone. Palm will release an update soon to fix the hiccups and the app store will follow in a month.
