Also, Quest can draw a boundary for your playspace, erecting a glowing blue "fence" to show your safety zone -- but it won't sense when new obstacles have arrived. You've been warned. But: if you peek outside your play area limits, passthrough cameras show your world in black and white. It's cool! (And useful.)
But, Quest is still locked off from other ecosystems. It won't integrate with Android, or Windows. It runs whatever apps it chooses to run, and while there's 64 or 128GB of storage, there's no SD card slot.
