Design and aesthetics should be aligned for optimum function. Perfect design will almost always align perfectly with something that is aesthetic. Look at the form function of most phones, design and aesthetics have reached a singularity. Compare to the apple mouse, superficially ok, great superficial looks, but poorly designed as it does not do the job as well as a well designed product should.

The iPhone's invention was the result of deeply intentional design.

I do agree somewhat however; it is a pointless obsession to put aesthetics over function. The macbook 12 inch's keyboard is a case that proves your point.
