Robert Scobel (sp) did a comparison on Google +. On some photos I'd give the edge to the iPhone, on others, the SGS2. It wasn't necessarily the most scientific comparison, but then people who get the iPhone aren't necessarily looking for the best camera they can find on a phone.
GCMS, this is how I explained it to someone asking me about phones. So my wife LOVES coffee, so much that instead of doing the old MR. Coffee or a coffee maker, she grinds her own beans, has a french press, etc. Infinitely better cup of coffee. You pick your beans, the temperature of the water, how fine the grind is ... infinitely more control than say an instant machine. But despite that, I can almost guarantee that they sell more instant coffee machines than french presses. Why? Ease. Simplicity. No effort involved to reach the end result, which is a cup of coffee. Add water, open a can, push a button. Boom. Coffee. My wife goes through a few more steps, and would argue achieves a better result.
But then, my wife has a Nexus S, and not an iPhone.
We can argue about customization and flexibility until we're blue in the face. Until they experience it, they won't understand. And by experience I mean someone sits down and show them what they don't get with what they have. And even then, they still won't care, because a good percentage of people just want to push a button and get their coffee. Or go to Starbucks. No fuss, no work, no effort. And there isn't anything wrong with that. It's their choice. We just get a better cup of coffee than they do =) ...
