With two little girls, and constantly being in "kodak moments" I use this at least daily and the new shutter speed constantly. Granted I delete multiple pictures that end up being to blurry from the 5-6 I take at one time, but I usually end up with a keeper or two as well.
As someone who thought OS 2.0 (wans't called iOS back then) was the best ever, I think 5.0 is the best since then. Easily, this is one of my favorite features in iOS 5.0
