i love it when people dont even understand what symbian is and immedietley say its old when in fact what they are talking about is s60 which is just a interface layer sitting on top of symbian same as UIQ and that japanese solution.
coincidently all 3 no longer exist b/c they have become one by being contributed to Symbian foundation unifying the platform and making it open source. we are set to see a new UI by the end of 2010
