This is excellent. I know many people for whom this would be cheap enough to just add on to their next phone contract, who otherwise wouldn't have dipped their toes in it.
As an aside, I really wish Google and Oculus could get together and work out how to allow Cardboard apps to take advantage of the extra hardware from the Gear VR if it's available. Using a Gear VR and then trying Cardboard shows how woefully inadequate Cardboard is; but there are some cool Cardboard apps that I'd really love to be able to try with the much much better tracking of my Gear VR.
