Never cared for surround music. I have never been to a concert where people played behind me except for a few rare occasions where they played wireless and entered from the rear or ran around the venue.

As for movies, the more people I talk to are not interested in multi channel setup due to placement, amount of room needed, WAF, and other factors including getting it setup properly and maintained. I would say mostly us gearheads are the ones still doing it. I even opted for a ZVOX unit for the bedroom instead of another 2ch or 5.1ch setup.
