Polk Audio miDock

Battery or AC power; recharges docked iPod; iTunes syncing via USB; line-in port guarantees compatibility with any audio source.

Nothing more than speakers--lacks radio, clock, and video output; no EQ; remote feels cheap and is unresponsive.

The Polk Audio miDock Studio sounds good enough, but it lacks many of the extra features found on similarly priced competing iPod speaker systems.
