FWIW, one of the serendipitous advantages of the disadvantages of Google Cardboard - is that being hand-held and not strapped to your head, it's a lot less of a problem because people tend to consume it in non-nauseous amounts - it's really common to see Cardboard users pull them away from their eyes every 60-90 seconds and say "man, this is awesome!" before diving back in. This means even though the headtracking is significantly worse on many phones than even the GearVR - it's super easy to "reset" your inner ear and head balance.

This is obviously content-specific, it won't help at all in a 3D fpv shooter where taking your attention away for even a second or two means getting headshot, but it works well for "along for the ride" content (like roller coasters, sweeping landscapes, and presumably skateboarding or roller blading down Lombard St)
