Remember not to take this site too seriously, but in re unheard melodies cf. John Keats, "Ode on a Grecian Urn." In your case I agree that hearing music is part of your workday, but in general I do not see the need for players or cameras on converged phones, especially if they require the device to be worn on the belt and/or have an exposed screen, rather than closed in the pocket and always be with you, even when you do not want to look geekish.
