The problem is that Bluetooth headsets are universally shitty devices. You <i>only</i> wear them to be conspicuous, and by now everyone knows the emperor has no clothes.<p>There is a lot more money going in to HMDs than Bluetooth earpieces. I would not be surprised to see an AR headset, about the size of large pair of aviator sunglasses, on a model on a fashion runway in 2 years.
