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!"
Thats great but they fail to mention something I find most important about memory cards - POWER CONSUMPTION.
Do these Sauced up cards suck the battery up faster than the less saucy ones? If so how much? Last thing I want is a fast card in my Phone/PDA that sucks the battery down in half the time....
