I've opened mine up, (M13s) and there's enough electronics in it that I didn't want to put in the dishwasher. I need to debug the trackpoint on one of them (it's simply not working, might be the cable, might be the driver circuit) and the ujm keys on the other one. I found washing the switches with alcohol worked for a while, but I'm still getting miskeys on m j and u, where m -> m, u->ui, and j->jk.
