The problem that the bright research and development boys of SE refuse to see and hear even if it's right in their face and consumers have been screaming is that their Walkman phones: DO NOT HAVE 3.5 MM JACKS AND ARE NOT OPEN TO CHEAP MICRO SD CARDS!! This elitism, protectionism and selfishness is their downfall and they are losing to Nokia in this regard. Serves them right for attempting to create their won niche market and dictating the customers what to like rather than listening and obeying what the customer wants!!!
