Lethal said:PC offers a virtual headset that turns yours games into 3D. The expensive one is frickin awesome. This is something the consoles dont offer. Dont compare PCs with consoles people.
Not 100% correct, but I understand what you mean, sure.
Atari Jaguar had a VR headset, there was an E3 where you could actually use it so it was definitely operational and not vapor-hardware. Never went into mass production apparently.
Virtual Boy rings a bell, too.
