Smart Widgets

Google makes the App section smart by introducing “improved App Widgets that can automatically resize, based on where the user drops them on the home screen, the size to which the user expands them, and the amount of room available on the home screen.” New App Widget APIs let you take advantage of this to optimize your app widget content as the size of widgets changes.

So the widgets in your Smartphone will become responsive.  If you drag and drop any widgets into the home page, the OS will manage home screen space by adjusting other icons and widgets to make space for new ones. Apple has not embraced widgets in iOS while Microsoft has taken a step towards it by creating customizable "live tiles" for Windows Phone. But they are still static boxes tied to a single home screen. Android's widgets are now smarter and will be easier to integrate on an Android's variety of home screens.
