Each wave of computing changes not only how applications are made, and the economics behind them, but our concept of what they can be. The Post - PC Era is defined by the rise of 10 BILLION mobile devices converging in a global cloud that is social, service oriented and massively scalable. By looking at Post - PC as a medium that is distinct from the PC and Web, we can envision new types of 'native' experiences that are dynamic, data-driven and media rich. This presentation looks at the ramifications of this wave, including key industry trends and a real-world case study of a series of applications built upon this model.
