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!"
We found the LG Chocolate Touch at Best Buy for $49 w/2-yr contract on 11-14-2009. So far, 13 hours later, we think they are pretty neat. Hubby calls them "iPhone-Wannabees." But without the required internet access charges. We added minimal data access for $9.99/month to each phone to see if we really wanted it.
Also switched back to lovely Verizon coverage after horrible coverage by AT&T.
