Computers and databases, mobile telephony and SMS texting, the Internet and email, digital broadcasting and satellites: all such mobile technologies feed directly into the performativity of mobile lives. Yet digital technologies also facilitate the mobilization of feelings and affect, memories and desires, dreams and anxieties. This mobilization is very complex and contradictory at the level of the self. Communication technologies underpin an increased digitization of social relationships, but they also imply a broad and extensive change in the way emotions are contained (stored, deposited, retrieved) within relationships at a distance. This article builds upon the notion of ‘miniaturized mobilities’, as detailed in the theory of mobile lives, and draws specifically from psychoanalytic theory in order better to grasp contemporary transformations in the storage, containment and retrieval of affective states afforded by new information technologies.
