"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.

It needs to be small, but mostly, just really quick in operation. Thanks!"
"while automatically configuring the interior with all your custom in-vehicle settings such as radio presets, mirror and seat adjustments, etc."
Just FYI, keys for BMWs and Mercedes and just about every other manufacturer these days already do this.
