After reading that article, three words come to mind: OH HELL NO.
You get one of these things, then one hour later, the augmented reality will start popping up real-time ads. Think Layar and when you walk by a Starbucks, it sees the logo and has some 3D person telling you the specials. You walk by a grocery aisle and today's sales invade your vision. You walk by a stripper club and--well, that last one sounds good.
If you think ad popups are bad now, wait til these things are out there. Hopefully the eggheads at Google will figure out an image recognition that will see a red light or the red "Don't Walk" images and pop up a huge "HEY DUMBASS THERE ARE METAL DEATH BOXES WHIZZING BY" sign in the wearer's vision.
