The price of these hasn't been announced, but the competitors cost 600-800$. That's a bit much for me.

That they're a lot lighter and smaller than full-fledged VR headsets is nice, but they're also more expensive and lower-featured, so that's a tough sell.

One thing I like about them is that they're really just dumb displays rather than requiring a connection to the Facebook servers or some other dumb stuff that will ensure a limited life time and limited user control about what they do.
