How do you know how much it costs to provide an extended warranty? If it actually costs money, that kind of rule would make devices more expensive for everybody.
I am OK with everybody paying +3% more than few unlucky ones paying another 100% because they received faulty pieces.
In EU there is mandatory 2 year warranty for everything (with exceptions like food etc) and maybe extending to at least 3 years could be fine compromise.
2 years warranty is enough to sort out the faulty pieces. Is there no warranty in the US? In any case, obviously that kind of insurance costs money. Why not let individuals pay for it if they want it?
