The benefit to electronics is all selective perception
LOL. That phrase does not mean what you appear to wish it meant.
I make my living at various applications of electronics from a very wide range of years. I appreciate the things that permit service. If the manfucturer will provide documents that allow me to service easily, that's a plus. If I have read the circuit board to see what's going on, I can still do that, but I can't imagine replacing a failed electrolytic capacitor on circuit board, on the side of an interstate while we are already late getting to cousin Jeryld's for Sunday dinner.
