I know it means nothing but I'm in the 5%. I've never had a case on my iPhone and I've owned every other generation since the original (I always skip generations for my devices since they started doing the incremental S versions). I prefer things without cases and the AirTags are going to be no exception. I'm going to throw them into a pocket or put them into an already existing spot so I like that it's thin.
What are you going to track without using some kind of holder?
Personally, I only bought one AirTag (along with an Apple leather keychain, for my keys). I don't generally lose items large enough to have some kind of pocket/holder for an AirTag (e.g. I don't ever lose my backpack which has a zippered compartment to hold random junk).
