That may not even be where the devices are most toxic to the environment :\

How about all the energy waste for manufacture of what are "engineered" as effectively disposable components & assemblies in numerous facilities?

Also scattered local emissions, not only at the factories and delivery ships & trucks, but consumers kick up all kinds of exhaust and waste just earning the money to participate in such a scheme. And way more so for short-lived products that are the least bit overpriced compared to how they could be from the same factory.
