In the 80s I had a keychain whistle finder. I.e. whistle twice and the device responds by beeping. It seems the AirTag is similar technology but 10x as expensive, with only little more real value. Am I missing something?
The part where this works globally and is not constraint by how loud you are able to whistle.
With this, it's every populated place. They won't work if you lost something on a back country hike, but 95% of the world (that you'd visit) will have other iDevice users pass by within a day.
Also, I don't see how you'd lose something so important that you'd tag it. E.g. I'd tag my camera, but then I wouldn't lose it because it is precious to me.
Clearly.
