Geeks are often so engrossed in scrounging new things that they don’t even realize if ever their expensive gadgets are left behind or misplaced by them. To alarm such lost tech-geeks about the potential theft of their precious

gadgets, a Bluetooth-based alarm system has been designed by a firm in Edinburgh. The virtual device, called Nio, is merely of the size of a keyring, which buzzes whenever your gadget gets a certain distance away. The nio uses new software that has been designed to link with your existing Bluetooth enabled mobile phones and PDAs. The device is currently available at Bluenio.
