This is one of the great things about buying an Apple Cinema Display. My Displayport model provides audio/video over one cable, camera/microphone over another, and a third MagSafe connector. The Thunderbolt design allows for audio/video/camera/microphone/ethernet/firewire/even more thunderbolt, plus a magsafe connector. I think we'll see a lot of small USB hubs with a USB-C connector to your laptop and all your USB/audio/Displayport/ethernet out, so that getting back to your desk is one cable to plug in and not a half-dozen.
