Otavio - for years I used to carry around a 4 or 5MP point and shoot camera in my briefcase so that I always had it with me should a photo op present itself. So long as the lighting was reasonable and the subject wasn't moving (it had a terrible shutter delay) I was able to get some very decent shots. On the other hand, the moment the shooting conditions were less than ideal, forget about it.
I think the who iPhoneography movement out there today is taking this principle to an extreme. There is a lot of truth that the person standing behind the camera is what is most important in getting a great image. But only if the shooting conditions are good...
