vive la difference Alan.
It's amazing how many people I tell about software applications like 'Spotify' who have never even heard of them.
Itunes seems to have caught the public eye (mainly as a by-product of the Ipod and Iphone IME), but computer audio as you state is at the starting gates of something huge.
Reading a recent interview with a Microsoft Director, he spoke of the changes in audio and video we are likely to see when the humble television becomes more of a computer, and less of a monitor.
Interesting times.
*edit*
As a matter of opinion - I believe someone wanting to attach an apple airport express and their television directly to some active monitors has every right to be as 'part of the audio scene' as any quad, valve, Linn or Naim devotee.
We either include or become secluded, and I want to see a bright future for the quality of music production in people's homes, no matter what avenue they pick.
