That isn't like Google at all. Apple is divided up by function, Google is divided up by product. So the Android team has it's own designers, as does Chrome and Search. Whereas at Apple the same design team works on all the products.

I'm imagining a company where each product group hires the designer group...

Apple's functional structure sounds like a good way to maintain consistency across product designs and nimbleness of corporate strategy.

Google's (and Microsoft's) product-oriented structure sounds like a good way to have fragment product designs and strategies and create political fiefdoms. "The Innovator's Dilemma" suggests that by placing too great an emphasis on satisfying customers' current needs (with existing products), companies fail to adapt or adopt new technology that will meet customers' unstated or future needs.
