Don't Apple wall warts have only two prongs? It doesn't matter if the outlet is grounded if the device doesn't use the ground pin.

You can get an extension cord for Apple (computer) chargers which also carry a ground signal. Highly recommended.

Typical Apple, making you pay extra for something that should come standard.

It used to be standard. I don't know why they stopped including it. Well, actually I do know - $$$

There's a large ground under the removable power plug in iPad/Mac chargers.

It can also, possibly intentionally, be used as a bottle opener.
