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 have a panasonic powerline adapter setup. I bought it so I could connect my downstairs xbox to the router upstairs. It works very well, but one thing to test for is how well the unit works when other devices are being used. At first, the panasonic setup failed to work when lights turned on/off and other small appliances were used, but I guess it has some software that has to learn how your house works. But it fails when I run something high powered like an electric lawnmower or the dryer.
