I'm interested in what this could offer me. I'd like to have it as a smart device maybe that could benefit me fitness wise and music wise. I doubt the bone conductor will be a good music device, but in a pinch, it might work. Maybe I could replace my contacts with prescription GLASSes, probably not, how bout sunglasses, Yeah that'd be cool. 300 Dollars would be a good price IMHO, It's pretty well "crafted" and would pair great with my Nexus 4.
