Jobs himself liked to use the example of typography. He took a typography course on a lark, and it became a core differentiator in Apple products.

In an age where computers were only capable of printing utilitarian, fixed-width typewriter text, Apple made a computer that could render text in the same way it's published IRL. Jobs specifically cites this during his Stanford commencement speech:

I think it's clearly seen in the focus on design details, software flows, abstraction of technical configuration, focus on Music, Art, Media, etc.
