It doesnt? Massive headset, hand held peripherals?
But that's like comparing the Model T to a Tesla. What? They both have 4 round wheels, a steering wheel?
As I said, it didn't take off, in fact disappeared in the 80's because it was terrible. Did you try one? (So, even worse than the car comparison. The Model T could function as what it was intended to do, the VR from the 80's couldn't)
