Eos' new iPod Speaker System is like a Sonos for your iPod. Dock your player inside the base station/transmitter and then place the accompanying wireless speakers wherever you want. The Eos base station will wirelessly transmit music to the speakers up to 150 feet away. You can have as many as 4 satellites ($129 each) going at once. The system will be out in March for $299 (includes 1 wireless speaker), but unless you have a big enough house, you might be better off with something a little cheaper.
