There is nothing sweeter than an iPod dock that has no wires. Wireless is the way to go. Make that same iPod dock usable in different rooms, then you're sitting on one cool dock. The Sony S-Airplay Wireless iPod Dock does all of the above. It's a cheaper version of the Sonos home audio system.
Basically, the iPod is plugged into the central base station. Up to 10 wireless speakers can be managed this way, in more than one room. The S-Airplay will transmit up to 164 feet away, has alarm clock functions and an AM/FM tuner. The central docking station can be connected to your home theater, allowing other playback methods as well.
The S-Airplay is available now for pre-order for $400 in the Sony online store, and will ship in September. The price includes one docking station and two wireless speakers.
