Road warriors come in all shapes and sizes, and their equipment reflects that diversity. Nowhere is that more evident than the stalwart mouse, where functions can range from built-into while looking like a the whole time.
But those who truly love to boast of their worldliness would probably want to get one of these: a GPS wireless mouse. The Bluetooth Navilock BT-451, according to OhGizmo, has been released for would-be Magellans on the European market with a "SuperSense" chip that's capable of indoor and outdoor tracking.
Why one would need a GPS mouse is well beyond our comprehension, of course, but the farthest we travel these days is the local Wi-Fi doughtnut shop so we're not exactly experts. We do know, however, that we would't want to carry around a mouse shaped like a maple bar, tracking or no tracking.
