I'm not thrilled about the 'display on a stick' concept.

Feedback mechanisms to compensate for eye movement relative to the VRD can only do so much, which limits the range of allowable movement. So it must be held in a fixed position, either by your hand in the case of the personal data communicator or from your head for the wearable PC. More conventional microdisplays that use magnifying lenses also have this limitation. You lose freedom of movement relative to the display. That makes it a lot more intense than a direct view display. No problem, though, if you're a borg.

In 'augmented reality' applications you have almost a normal field of view around the device, which provides only the augmentation. Instead of staring into the device, you're concentrating on the task at hand and the augmentation is an overlay, a small addition to the total visual input. You can tell from Microvision's partnership deals that this is the most promising niche for them. Especially where cost is no object: surgery, military heads-up displays, etc.
