Tim Cook doesn't seem to care about anything other than the supply chain. He came from being a COO, so that's all he knows. Consider how many different models of iPad there are.[1] It's like he's bragging. "Look how good we are at managing suppliers. Look! LOOK!" Meanwhile, the watch, Apple Music, and everything else that reached a v1 release under his tenure so far has been buggy and broken. But hey, at least they have a "gold" Macbook now!
