This document provides an overview of a talk on mobile strategy for product designers. The talk discusses how mobile is the most widely adopted technology ever, disrupting industries like entertainment, commerce, education and more through dematerialization. Mobile and the combination of connectivity, cloud computing and smartphones has transformed how people access information and services. Entire industries like newspapers have been disrupted by smaller mobile-focused companies targeting different parts of their business. The speaker argues that mobile disruption could also impact other industries like restaurants that have yet to fully embrace a mobile-first strategy.
