A toaster is probably a bad example, given the common error states (burnt toast, stuck toast) which are no doubt amplified by design flaws in some units. I've never seen a toaster with 2000+ components, so maybe such a machine is different. A toaster is also historically famous for a dangerous error state: if the plug is inserted the wrong way round, the coils will be switched on neutral. A toaster which is "off" is thus liable to shock an unwitting person using a fork to resolve the stuck-toast error state.
