I'd like the button to be harder to activate, like when your keys are in your pocket. Mine set my phone off when I was sitting in the audience at a local planning and zoning meeting, which was the last straw. As soon as AirTags were available, I ordered one. My Tile then went in my laptop bag.I actually prefer Tile for its feature of clicking the tile rings your phone which is an immensely useful feature that Apple should not have left out on their product. Tile’s future may be bleak, but it’s not dead yet.
The QR code sounds like a good idea, but it'll wear off after awhile, and become unreadable, unless there's a durable clear overlay over the label.
I think Tile can still be viable if they can get around the accidental button press issue, and lost device finding improves. The next AirTags need to have a louder speaker - Tile definitely has the advantage there.
