Back in 1998 it all seemed so simple. Mobile handset technology was about to explode; therefore, to pre-empt any interoperability problems, the industry needed a standardised operating system for the new breed of "smartphones". This would allow developers to write compelling applications for a wide range of devices. There was a brief but exciting tussle between Microsoft and Psion over who would contribute the core technology. Psion's EPOC won, and Symbian - an operating system controlled by a consortium of device manufacturers - was born. Is this the end of story?
