Mobile devices and services have achieved a level of critical mass and importance that requires us to take them seriously as new cultural resources. Mobile cultural resources emerge within what we call a ‹mobile complex›, which consists of the interplay of structures, agency and cultural practices. These new cultural resources also can be considered to be valid learning resources which are ‹complex› because the components of the triangular structuration model, that governs them, interact with each other in intricate ways. They are in a state of perpetual flux, where boundary blurring takes place and where society and culture are experiencing the delimitation of mass communication.
