I haven't seen any point or use to this project since..ever.
Who wants to be wearing some glasses all the time or having to take them out, open, put them on, to give'em a fair use? I mean, I'm sure they could be nice in some very specific scenarios .. but I don't see it as a revolution on main/personal devices,..
For that to happen, we would need a contact lense solution, and even those seem too complicated. They'd need to be implants. I know it sounds too futuristic, but this is the reason why I think smartphones will remain as "personal computers" for many years still.
