Griffin ahead of MacWorld in San Fran has launched a number of accessories for the iPod. The most notable of which is the AirClick, a remote control unit for the 4th gen music player.
Purportedly able to work over a distance of up to 60 feet the unit uses RF signals rather than Infra-red to work. The five button remote allows for play/pause, next track, previous track, and volume up and down. A hold switch on the side prevents accidentally disturbing your musical nirvana.
The remote also has a clip on it for convenient attachment. iPod and iPod mini packages include a convenient remote holder with velcro straps to allow attachment as an armband or to a bicycle frame or steering wheel.
You can get the device for the 4th Gen iPod, iPod mini as well as a USB dongle for Mac and PCs.
