And read http://gadgetwise.blogs.nytimes.com/2011/09/04/two-thin-cameras-packing-fat-lenses/?_r=0 for example notes this one has a " It also tries to eliminate shutter lag with what it calls "a pre-shooting cache." That means the camera starts taking pictures as you begin to press the shutter, instead of waiting until it is fully depressed, because most nonpros tend to shoot a beat too late. Continuous shooting mode grabs shots at up to six frames per second."

Maybe that's a feature you want?
