I also heard you Keith, having a couple of expensive appliances that died before their time due to c.b.'s.
I think manufacturers don't consider enough the "rough service" of c.b.'s - particularly vibration & heat. So, it's not the electronics, it's the design.

Car parts are "rough service", and I expect the airbags, ABS and Antiskid systems to last the 10 years (20 years in Calif) that cars are capable of.

Finally, the electronics & digital world opens up functionality - - a programmable thermostat is made possible by electronics, but I don't need to use an Adroid app to call in to a home controller to change my thermostat settings -- maybe in 10 years when I get my "TV everywhere" and network & cloud media system working.
