Symbian S60 was limited in Touch. There was Symbian UIQ optimized for touch screens, its 1st smartphone was Sony Ericsson P800 in 12/2002. But UIQ was ditched in 2008, only Symbian S60 was the choice for Symbian Foundation. If Symbian UIQ had been maintained, it would be better UI to dispute with iOS and Android in 2008-2011.
