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 called them and they have USB extension cables for use with the device for under $6. They said they would soon have a 'Y' cable {two USB-A to one USB-A female} to provide more current for 3G wireless cards. They said it improves transmit and reception for some of those cards.
