My revised home screen experience uses tiles of information intelligently grouped by context, like say, what you're doing. That's why you'll see groups like, "My Morning Routine," "My Upcoming Commute," or "Recent Social Activity."
The tiles serve as a platform for applications to deliver contextual notifications. Users can customize preferred tiles and their priority -- the user stays in control of what they want to see when. Sections are customizable, too.
