If you're one to play your Xbox games sprawled out on the couch, legs akimbo and controller wire snagged around you ankle, you might want to consider a 2.4Ghz Wireless Controller from Hip Gear. Then again, maybe not.
This thing offers no advances in wireless technology, relying instead on the unimpressive, cost-effective 2.4 GHz spectrum of the common cordless phone.
It eats AA batteries like popcorn, 4 at a time.
It's got some cool macro programmability and it's sturdy enough, but it does not accommodate your Xbox Live Communicator headset, which must be tethered to the wireless receiver, which plugs into a controller port on the console. Ergo, pointless.
