Slate

In the book "Design Forward," Hartmut Esslinger says that being in the company of coders (and their monitors full of abstract-looking code) inspired Slate, a concept computer filled with lines and bar-shaped accents -- shedding the hard angles of past Apple devices. After shipping all of the prototypes to Apple, the two companies agreed on the Snow White design language, which often used white as a base color and focused on "lines, slates, and no angles."

The book sheds light on the finer details of Snow White design:

Slates with a zero-draft character shape, minimal surface texture, no paint, minimal transitional angles when needed (monitors), and volumes/sizes as small as possible.
