Accessory manufacturer Kensington has produced peripherals for computing aficionados for years. A new gadget by the company is the Kensington Proximo security system, which leverages the Bluetooth 4 technology found in Apple's latest crop of devices and promises that the fob-and-app combo will help prevent expensive mobile device loss. Electronista was given the opportunity to evaluate the new technology, and put it through its paces over the last week.
