If Your Cell Phone is a Digital Leash, This is a Leash for Your Leash.

I remember when people used to complain that their BlackBerry was a "digital leash." While useful I can't help but think this ensures you always have your leash with you. It's like the ankle bracelet of mobile electronics.

Zomm unveiled a Bluetooth wireless leash. It will sound an alarm if you walk away from your mobile phone, making it easier not to forget it somewhere. The Zomm device goes on your key ring and is wirelessly paired with your mobile phone via Bluetooth wireless. If you walk out of range, Zomm will vibrate and flash lights. It will also provide you with a sound alert for incoming calls when your phone is out of sight. You can answer a call by pressing a button. Then you can use Zomm as a speaker phone.
