That's a good one. The first thing I noticed was "it's all about motion": sliding to unlock, launchpad icons zooming into view, swipe-to-scroll, a keyboard popping up, a pin dropping onto a map, the screen rotating to the right orientation, turning a page... And, in another layer, the people are all in motion in some way: some just their hands, a child's feet, someone on a bike, someone on public transportation, the implied motion of being out at a coffee shop, or just sitting out on your front steps.
