70 degree FOV is such a deal breaker for gaming. That and the price. In a world where people already have tons of screens, monitors and TVs in their face - the practical use case for this is relegated to trains and planes. Very niche.
Not sure where this lands functionality wise. I feel like it's most direct competition would be as a cheaper Apple Vision. You would need to pair it off with a Windows system for heavier productivity work most likely. Even though their OS is "android", it doesn't have the Google ecosystem behind it, let alone matured on that front. Media consumption on the go seems to be the other use case.
So, compare them to either XREALs plugged into a laptop/phone, or Apple Vision Pro I guess.
