However, this isn't really what Oculus is doing here. This isn't a "cheaper version of Oculus Rift". This is an expensive version of Gear VR/any Android Daydream headset.
It has some extra sensors and whatnot, but other than that, it should play the same content. So how are most people going to understand the difference between a $60-$100 Daydream headset and a $200 Oculus Go?
At least the $600 headsets actually offer you a different kind of experience (realistic 3D games, etc), even though their price means they'll be relegated to an early adopter market for a few more years.
