The switch

Apple’s AirPort Express features a great technology called AirTunes. AirTunes allows music to be streamed from you Mac to the speakers connected to the audio port on the Express. The only hitch is that you need to use iTunes to control the music - if you don’t like a song, you need to get up from the couch, walk over to your mac, change to song and sit back down again… too much effort!

Why doesn’t Apple make a remote control for the AirPort Express? I don’t think there is a valid explanation. To help Apple to make this great , you can pester Steve Jobs right here: sjobs@apple.com. Until then, Griffin Technology presents you with a reasonable alternative: the AirClick. The Airclick is available in two editions - one for the iPod, and the other one for your mac.

AirClick USB is a remote for Mac and PC computers. The receiver module attaches to any available USB port and receives signal from up to 60 feet away. AirClick USB is ideal for controlling applications including iTunes, QuickTime, and even Keynote or PowerPoint.

AirClick uses RF signals that travel through walls for control anywhere in your home or outside, up to 60 feet away. 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 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.

The downside: the AirClick costs a hefty $40
