Cordgo - iPod Cord Detangler!
Okay, I have to admit two different things. One is -- I hate tangled cords. With a passion. They drive me nuts and make me go slightly cuckoo. The second thing is -- I bought one of these CordGo gizmos, and it works great. It keeps my iPod headphones tucked away nicely, and keeps me safe from tangles, knots, and insanity.
