Apple is becoming like Bentley (or similar higher-end car manufacturer), where the improvement is not in the feature but in the overall package. In other words, the package you get is the feature.

Some improvements like fit & finish, tolerances, endurance, so on are not visible on paper. Others like battery life and weight are visible on paper. When these combine with the xOS (where x={mac, i, iPad, tv}) ecosystem, whole thing becomes visible or palpable, one may say.

It's not an ubiquitous thing to have in technology space, and only possible with tight integration Apple provides, and strives to keep.
