The wrist as a wireless hub

Imagine a wireless communications hub that you can take wherever you go, on your wrist of all places.

That's what Hewlett-Packard envisions, a "personal area network" that could handle any manner of connection required to run a wireless device, whether it be Bluetooth, Wi-Fi, WiMax or 3G, according to our cousins across the pond at CNET U.K. The concept involves a silver cuff hub that resembles something out of a Tiffany catalog. Or it could look like something else altogether, like a credit card.

The reason for the ambiguity is that Phil McKinney, chief technology officer for HP's personal systems group, says a wearable wristwatch-like hub won't be available for purchase until 2016. But it's a worthy idea, and, besides, we liked the artist's rendering.
