Symbian Belles UI is great and also much much more fluid and responsive than S60v5. and there are many things that Symbian can do but Android can't. one example is that open google maps and search for a place and put it on background and your Android phone will lose gps lock. where as in Symbian this never happens. and in Symbian you also can play music in background while talking on phone. a feature which none of today's phone have.
