I first came across this video will browsing venturebeat.com and I was blown away by how cheap this are compared to google glass. Also they differences in design for these glasses. One main thing was how the information your looking at will be in front instead of off to the side. They also I believe were going to have the capabilites of prescription glasses. The overall and visual look of them could be improved a bit with the frames but that could just be me.
