I've used it at many places in NYC: Walgreens, Duane Reade, Whole Foods, McDonalds, a local grocer, vending machines, Apple Store, Best Buy. An important point is that Apple uses a token and not your CC for paying and thus you protect your CC from hacks. When I tell people this advantage (Do you remember Target, Lowes hacks?) they are very interested. You can also conveniently look up your last few transactions on the phone.
