A design for disaster

Take a look at this. Just let it soak in for a minute. How many ways could this little gadget get you into trouble?

Now I've run into doors, walls, cars, and other people just by walking while I check my phone for email. Imagine an office where people are zooming around on these little babies, eyes glued to their laptops, and (for good measure) earbuds probably stuck to their ears.

Don't get me wrong... it would be hysterical to watch (through a tempered glass window set into a cinder block wall), but I have to wonder what the designer was thinking when he or she came up with this.
