I can see this being useful if they add a camera to the front of the eye-projection part of the unit.

Then it can re-display what's in front of the user's face with captions like the AUGMENTED REALITY through Yelp App on the iPhone (http://www.engadget.com/2009/07/24/iphones-augmented-reality-apps-coming-with-september-os-3-1-lau/)

It can get very interesting from there... if the military is using in the battlefield then the soldiers can pretend their back in their mother's salon playing Xbox360 and just look for the HUD indicators with the highest kill points.

...if it's coming to hospitals and surgeons are using it then it can come with zoom functions that shows "slice here dummy." In fact, it can be branded by IDG Books as "The HUD Surgeon for Dummies" book.

ok, now that your tongue has been placed firmly in cheek. I think there is some grain of "reality" to the scenarios I just described.

can't wait to see... :-)

Something like this is useful for when you're lying down and don't want to hold something (phone, mid, netbook, etc.) over your head with your arm(s). Should be great for reading in bed. I'm sure you can think of other uses, too.

So we can all take Golden-i showers. ;)

Looks like a Borg to me. Is this how it begins?

I guess you need it if you want to look like a bigger douchebag than "Bluetooth thingie always in the ear guy."

As if I didn't already have enough people walking into me at the airport while they're wandering around playing with their Blackberries, now they'll have a computer screen strapped to their face.

Maybe it's time to unplug.
