The document discusses future directions of smartphones and mobile development over the next five years. It predicts that smartphones will become as powerful as servers, incorporate more advanced sensors, have improved displays, and support new interaction methods like voice and near field communication. This increased capability will drive the need for new mobile development tools, APIs, and standards to build applications that can take advantage of all smartphone features across different devices. The success of app stores will also modernize the mobile development technologies used by the industry.
