The document discusses how consumers now use multiple screens simultaneously rather than a single device. It argues responsive design is not enough and that companies need to plan for users, not devices, with a content strategy that provides a consistent experience across any screen. An effective strategy requires understanding user needs, mapping their journeys, and breaking down silos between teams to optimize experiences for multi-screening. Examples that do this well include Apple with syncing accounts across devices and Audible/Evernote with seamless syncing of content.
