Preordered mine as a switch from Apple. Mostly because of the Daydream VR line, and I have found myself strongly disagreeing with a lot of Apple's vision. (Lack of VR, Lack of aux)
If you believe Robert Scoble, iPhone 8 is going to have like desktop-grade VR. Now mind you, I don't believe Robert Scoble, but the claim has been made, as if it was fact.
Wouldn't be surprised to see Apple unveil something similar to Daydream in the next year or two.
