To the original post I would say follow the dollar on the big picture side of things. Where is the money being spent?
I think of Apple and it ties to content.
Music and content first, systems later. I remember my mom propping up her suit case record player/changer in the kitchen, listening to her favorite music as she cooked. Or, singing along to the music on tape in the car.
She would laugh at me now, fretting over the next big upgrade to my system. I don't think I really enjoy music more then she ever did back then.
Is there a correlation? I don't know 100%. But It might only be valid from a marketing point of view to how much will it cost us to make this "box" and how many can we sell?
I think people would like to listen to music through something that is pleasing to them. But the experience of music means different things to different people, even if it is generally agreed that any decent stereo system will sound better a single speaker radio.
How much money do YOU have to spend to enjoy music? Ask everyone on the planet, or at least people who are adults earning a living with the kind of "problems" we have in a place like the U.S. The answer might just be a question: How much for the newest iPod?
