Might still be worked on at the phase they're at. I do wonder about the lack of an overhead strap in the design. In the pictures and video, the headset the guy is wearing is probably light and without a display to vertically align his sight on. I imagine they're trying to avoid the strap to make it more stylish to enable its use in public settings, but if it ends up being uncomfortable or hard to focus through, that would really hurt all other values it offers. It's meant primarily for work, so one should be able to stay on it for hours. Wonder how things will turn out. Worst-case though, adding a strap is probably not too difficult of a mod.
