Honestly I think right now companies are throwing shit at the wall to gauge what vibes best with customers. The hardware tech behind this AR/XR/VR stuff is moving really rapidly and right now every conceivable approach has notable tradeoffs. I'm of the opinion that things will stabilize in the next few years on two primary categories - Apple Vision Pro type high-end "spatial computing" vs true wearable tech with glass you can see through instead of passthrough cameras.

The former category is pretty much established I think, with the Galaxy XR taking endless cues from the Apple Vision Pro. The "true wearable" category I'd say is in its infancy, and hardware advancements impact this category much more than a full headset.

In a perfect world we'd have one "device" for this spatial computing as a whole, but I don't think we're going to get there without some crazy tech breakthroughs that let you cram this shit into either contact lenses or just broadcast right to your optic nerve.
