iPad or iPhone as a camera: C/D?

Now that the 3rd-gen iPad has a decent camera, how is this for general-use photography? The lens, now f/2.4, is reasonably sharp, it has good face detection and easily usable tap-to-focus, an adequate 5MP, HDR photos (via 3rd-party apps), and good low-light capability thanks to a backside illumination sensor. And though holding up a big tablet whilst shooting may look dorky, there are times having a huge ultra-high-res viewfinder, and the same display to view your pictures immediately, can be incredibly useful. You do have to get by without a flash (even an LED) or a zoom lens though.

Anyone here use an iPad for serious photography? How about an iPhone 4S, which has a somewhat better integral camera (8MP, LED flash, native HDR)? I'm seriously considering getting a 4S (or waiting for the next iPhone update) rather than updating my old Canon digicam.

I would say C, what do you want a zoom for?

a lot of photojournos use iphones

4S is classic
