Contrary to what everyone seems to believe I said, I never stated that one needs to carry a camera around either. The only times people would care about quality photos were photos of them self - which can be taken at home with a digital camera, photos of a vacation - in which carrying a camera is expected, or artistic/portraits and professional photos - in which your a damn idiot to use a cellphone for.
So and thus, the average user has no need for a 7 mega pixel camera for most of the shots they tend to take with their phone. If you do frequently take quality photos and are in fact a practitioner/student of photography, then it would also be expected of you to carry a camera. If you relied on a camera phone for that purpose, again your a damn idiot, unless you are artisticially trying to get a lower quality/rustic look to your photos.
Point is, guarenteed whatever your snapping with your iphone, its not significant enough to worry about the quality of the photo, and if it is, you should consider carrying a digital camera that would be better suited for your photographic demands.
Now a better argument would be, how come the iphone doesn't take panoramic shots by default like the Samsung Omnia and LG Dare do? (and yes I know about the Pano app)
