I took apart my Glass, added magnets, and have it attached to my eyeglass frame. Thing with mounting this on to frames is that you actually spend a lot of time micro-adjusting Google Glass.
This is all the real problem.
The real problem is just that Glass is boring. The UI is also really awkward. Voice recognition is pretty decent but saying ok glass ten thousand times a day is annoying.
Google still sucks at devices. Though they have the best VR compared to Siri. God, does Apple suck at voice.
