"(Earthing might be less important if you have an RCD-protected supply, but I still trust a wire fuse more than I trust a chunk of complicated electronics.)"
They actually do different things. An RCD will trip when there's faults which will leave a fuse unblown. Conversely, a earthing/grounding, will protect against conditions an RCD doesn't detect. (I'm not at all happy with my TV (quite new) which feels live whenever it is turned on at the wall. It's not going to injure anyone, but I do wish the metal on the surround was grounded.)
