"There are upwards of a million Pi's out there being used in industrial applications. You just never hear about it."
I hope not. Industrial electronics need to be tested for EM interferance resistence , failover states and whole host of other things that prevent the 50 ton press (or whatever) its controlling go out of control and kill someone if the control system has a bad day. Industrial control is a very serious business, up there with avionics - would you fly on an Airbus that was being run by a Pi?
