Appointment at Apple's "Genius" bar. Nothing much wrong with the mini, but the original charging cord is much taped and the nice long replacement one only works about every tenth try. Very satisfactory though - nothing wrong with the port and we get a freebie new replacement "lightning" connector. Is this because the staff guru next to us recognised J by his poppy as a fellow Canadian and told our guru to treat us well? Pretty decent, though. No longer under warranty from Apple, though John Lewis did sell it to us with an extended warranty.
