This $199 device not only docks and charges your iPod and iPhone, it is also able to deliver music stored on the device wirelessly without converting it to analog.
In addition, the Sonos Wireless Dock will play what’s stored or playing on an iPod or iPhone, including many music apps. With autoplay settings, the dock allows a user to select the zone (or group of zones) where the music will automatically play and the desired volume.
Multi-room playback is also supported, allowing users to wirelessly play the same song from a docked iPod or iPhone in every room of the house.
The dock is compatible with the iPod touch, classic, nano, and iPhone 3G/3GS/4.
