Good one. After reading this thread my list is: * Toilets * Bicycles * Water heaters * Locks * Guns The rest seem either a little too specialized, simple, or already in the process of being replaced by things with microchips. A few of these may be replaced as well (locks?), but it's not quite happening yet.
