This reports research on users’ attitudes towards and use of GSM devices and discusses the implications these have for the future evolution of hand-held devices. It argues that current usage patterns suggest that there is unlikely to be a widespread convergence of information accessing devices and person to person communication devices. It also argues that the latter devices and their associated applications could provide much richer opportunities for communication behaviours than is currently available, and that therefore design efforts within the mobile HCI community should focus on this rather than on information use applications.
