The document discusses the success of the iPhone and Apple's approach to innovation and design. It argues that the iPhone succeeded not just as a phone but because it created a new user experience by combining hardware, software, applications and social aspects. This allowed it to take on multiple meanings and transform the idea of a phone into new actions and experiences for the user. The document suggests Apple's innovation was based on the idea of "perfect incompleteness" and social heterogeneity, designing a product that could be completed and made unique by the user.
