Earlier quoted context omitted.
Good design is a fleeting, abstract concept that has more to do with correlation than anything else: Correlate something with good content and the design seems good by association. When it becomes common, though, it is ready for displacement. This is true of virtually every "good design" over the years. At the beginning people almost always thought it was superior in some way.

Were any other company responsible for making the new Mac Pro, it would have been met with devastating reviews. Correlation, however, and people somehow reach to find a way to make a case for why it is actually a good design.
