Personally I would compare these devices to be like the first monochrome display Palm Pilot "organisers" state of tech when what we want is modern smartphone.

Personally I would compare these devices to be like the first monochrome display Palm Pilot "organisers" state of tech when what we want is modern smartphone. The thing is too damn big, heavy, it obscures your field of vision, it gets hot and it has bad battery life. When will VR/AR really take off? When the headset can clip onto my prescription glasses and not make them too heavy. When any of my devices (smartphone, pc) Can use this AR display to show stuff on. Even then there will be a long time before AR will supercede classic high dpi displays.
