Good point Jeff,
But I think it's also because we listen to music in a different way these days - whereas 30 0r 40 years ago, a person would sit in their home a listen to a gramophone record on something that was part of the furniture. Nowadays music travels with us.
In the home, for a lot of people especially in apartments, a music player is a secondary device. We are used to driving our cars with a minimum of 8 speakers fitted as standard or in many case 10, 14 or 17 speaker systems PLUS of course with international headphone culture the stereo experience is certainly there. Of course, the fans on this site are not the typical home music system customer and will never agree to the little music player that fits in with the bijou apartment - although the A9 seems to totally defy this concept :)
In conclusion, the way in that the world is listening to music has evolved. When I was a lil shorty, 100% of my music listening was at home now it's probably less than 2% at the very most.
