How it works is that Google gets to use the successes in a later design and avoid the failures.
Rather, that's how it would work if Google were actually a hardware company, which they emphatically are not.
Say what you will about Apple but at least they admit they build hardware and aren't ashamed to do the R+D necessary to ship great hardware. They push the envelope and break it at times, but at least they don't do embarrassing things like 'hey, let's impress everyone with our design idea that will never ship' homage to someone's 20% project.
Also, Apple couldn't care less where you are or what you're looking at when using their hardware.
