I understand that Airport Express is due for a refresh soon.
I wonder how expensive it would be to add iTunes Match to the Airport Express as part of the "demotion" of the pc.
I know I can use Airplay to stream from my iPhone to an Airport Express or, alternatively, use the Remote app to stream from my computer to an Airport Express. But the first is somewhat taxing on the phone and the second becomes less attractive if pcs really do stop acting as central repositories for music.
Buying a dedicated match device solely for music seems unlikely to succeed but it could work as a bonus feature of an Airport Express (controlled through Remote, naturally). Sort of the way iTunes Match is a small feature of Apple TV. Given that the Airport Express is already internet connected and has an audio out, this is a natural feature to add (and continue to distinguish it from other routers).
