> I'm a little confused by this, aren't AirTag basically circular discs pretty much just big enough to house a CRT2032 battery?
Kind of. It's definitely the intention, but an AirTag is still considerably larger than the CR2032 within it [1], so they're not at a shortage of space in the shell.
As for "teardrop shape", I didn't mean to imply it had an elongated shape, but that it's rounded off on all sides, like a drop of liquid. The absence of any defined edges makes clip design harder and forces any AirTag enclosure to just act as a mini-pocket that contains the whole thing instead of having a simpler and less wasteful attachment method.
