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!"
While recording VGA to a big fat HD sounds nice, this is a really bad form factor for a camcorder. That combined with Archos' apparent lack of quality control, and I'm not even going to consider this one. The Xacti is looking good, though.
