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 am surprised no one else has mentioned this, but I have to call into a "free" conference bridge that my company uses, and as of about three weeks ago, if I use GV, it informs me the cost of the call is 25 cents/minute ! Ouch ! That isn't call blocking, but it stopped me from using them. BTW, for the same number, Skype just refused to route the call. No message or anything. I ended up making the call on my mobile.
