Ok, without mentioning the word "miserable" - oh rats, I just said it.. There's the technical angle of the inaccuracy of the original statement.
Apple seem to be using firmware updates on iPods and iPhones to prevent media players from accessing the iPod via the apple dock connector - so the original advert saying that they can play from said devices is , well , optimistic at best.
Ok, there's always the headphone socket I guess, but it means that the cueing facilities and pitch control are lost...you're back to play/ cue effectively.
