Griffin Evolve: As Wireless as Wireless can get for an iPod dock.
The Skinny A fancy iPod dock with speakers that literally lift off of the base unit and continue to work up to 150 feet away.
Geared Toward Those who must have their iPod playing at all times, no matter where they are in the house.
The Spin No wires, obviously. Ability to take your music anywhere without wires, the need for a power adapter or the actual iPod.
Counterspin Holy crap it is expensive. $350 or so when this speaker dock is released this summer. Because it is dual channel, you would need to bring both speakers with you to fully enjoy the sound.
Buy It If... You have a ton of money, are in love with your iPod and must have music in every room of the house.
