I went Cardboard (though used it very little, probably only 1 hour cumulative) -> HTC Vive -> Valve Index. I'll probably buy a Valve Index 2 if it ever happens. Portable VR is highly limited by battery power. VR requires high pixel counts and high framerates to be immersive, and pushing that many pixels uses a lot of power.
