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!"
So, my paying $1300 for my 42" 1366x768 LCD was a good thing, right? I'm still waiting to be able to do the same for a 42" plasma with a native resolution of 1280x720 or greater for the same price.
Hmm. 42" 1280x768 Plasmas (Philips, Toshiba, etc.) have been about $1200-1300 for a few weeks now at Costco. They dropped even further during Black Friday. IIRC, they're actually a few bucks cheaper than the equivalent 42" LCDs.
