Not the OP, but I probably go through a Microsoft Sculpt Ergonomic every 24-36 months. The wrist-rest also gets gross after a while. Mostly it's spills, but sometimes also a crumb or something stuck under a key and me breaking the switch in the process of trying to clean it. I think I also have one where I just physically lost the wireless dongle. I have some spare ones from the _other_ ones I killed, but AFAICT they're "securely" paired at the factory and there's no way to reprogram those.
