Do you think the photos taken with iPhones are not perfect?

The only technical flaw I see in any of those is the lack of shadow detail in the first one.

No one is saying you can't take beautiful pictures with a camera phone. In particular, when the photos are reduced to screen size, their optical limitations (chromatic aberration, lack of corner sharpness, etc.) are not obvious. However, these cameras can't compete with DSLRs in adaptability, nor in the amount of control offered over the picture-taking process. The DSLR can also get quality images in lighting conditions where the iPhone's camera can't. On the other hand, having a camera in one's pocket all the time is a great convenience, and means you will get pictures you would otherwise have missed.
