This is why I think that Google completely missed the mark on Glass. They tried to make it a stand-alone augmented reality device with camera, battery and CPU too. For people walking, all we really want/need is an inobtrusive head mounted display/headphones that clip to or are part of sunglass frames with wires down to the MHL or HDMI port on the phone or device. IMHO Google Glass had a great display methodology - it was the rest of the device that got in the way that was a failure. If someone made a monitor/display only clip-onto-glasses display wand that had a microHDMI for signal and a USB 2.0 for motion tracking mouse and power, but nothing else - I'd be in for that.
