Psion approached the other four companies and decided to work together on a full software suite including kernel, device drivers, and user interface.

This became a prominent point in February 2004 when UIQ, which focuses on pen devices, announced its foray in traditional keyboard devices, competing head-on with Nokia's Series 60 offering whilst Nokia was in the process of acquiring Psion's remaining stake in Symbian Ltd. to take overall control of the company.

This caused unease amongst other shareholders as Nokia would gain majority control of the company, with Sony Ericsson in particular being a vocal critic.
