Never lose anything ever again? - Nokia Locate Sensor
Don't get too excited, as this isn't a commercial product yet, but Nokia have shown off Locate Sensor, a tiny gadget that can be attached to anything precious and then which communicates with your S60 phone. If the aforementioned gadget then gets separated from you, you can track it down (direction and distance) up to 100 metres away. So perfect for keys, laptop, etc. There's a reverse mode, too, which can act as an anti-theft device. See Electric Pig for more info and photos.
That could be very useful in all kinds of niche applications, Nokia ought to advertise this, it's exactly the kind of thing tech journalists like to write about.
It's quite a step up from those whistling keyrings of the 1980s... :-)
