You dismiss the iPhone 4s in favour of a generic spec "compact camera".
Cris, I think you are perhaps missing the point that Bruno is trying to make.
Take the photographer completely out of the equation. Set the 4s up on a tripod pointed towards something interesting that will reveal strengths and weaknesses of a camera. Do the same with a "generic spec compact camera" so they are side by side. Set the auto-timers for 10 seconds and stand back and let each camera do its thing.
Then, compare the two images for sharpness, contrast, color balance, saturation, noise, depth of field, etc.
I think you'll find that the dedicated camera-only device will outperform the iPhone. And why shouldn"t it? You've got a larger sensor for less noise. You have a much, much larger lens area for light gathering and correction of aberrations caused by trying to squeeze all the lens elements into a 1/8" (or less?) long light path. I think it is miraculous that a telephone can take a picture at all, and that it takes a quite acceptable one is mind boggling. But just as I don't expect my point and shoot camera to do an outstanding job of making phone calls, I don't expect a telephone to make outstanding photographs.
I don't doubt for a minute that you can take better pictures with your iPhone than I can take with my very expensive, very capable point and shoot camera. But, we're comparing
cameras here, not photographers.
