Yeah, it's all in the bottle design. This is confirmed by hotels that favor it for minibars or other pay-per-use arrangements.

I remember it being pretty common and inexpensive in Fiji as well. At least it has that connection going for it.

Iceland has been trying to imitate the feat but hasn't come up with a good enough bottle design for the Iceland water.

I can't tell any difference in taste or quality. Might as well get Dasani, which uses those mysterious additives to make it taste more "watery."

BTW, going for a week on collected rainwater in the Cook Islands helped me better appreciate the "mineral" part of water that comes from the ground.
