I think it will be interesting to see how existing and upcoming Meta (FB) products compete with Apple products in the VR/AR space.
It seems to me like Meta might have some advantage here initially, but in the long run I'm not sure how it can compete with a company that knows how to really build an ecosystem on top of hardware that it engineers end-to-end.
I imagine cost might come into play here to start. I remember growing up and never having an iPhone because they were too expensive, and most of the kids I knew didn't have one either. It was all Android until one day I noticed everyone had swapped for an iPhone. Maybe Meta products will be the Android in this field, the device you get until you make the upgrade to an Apple product.
