Giving A Speaker Resonance

I'm imagining for $50 more, Apple could really have made a splash with the iPod Boombox.

Just prior, Jobs demonstrated zero configuration (automatic) streaming on the Mac Mini.
How much more and how much more difficult would it have been to put WiFi in the iPod Boombox and provide options to stream audio (for video too) using only the speaker, or in combination with a computer or television's attached speakers? Hello. Simple surround sound. That feature alone would have pushed me into temptation.

There is a lot of potential here. Why can't a computer set up and utilize a variety of speaker configurations. Why would anyone need a home theatre receiver, PVR, and a DVD player when they have a computer? I think the true killer app for the coveted living room space is speaker management. The XBox or PS3 could do the same.
