Also customers desire to keep their existing devices for longer, can’t afford a $900 device replacement bill simply because of a broken resistor/capacitor when their devices are damaged. You may argue they need to be more careful but things do happen.That goes against what consumers actually want (Smaller, faster, lighter, waterproof, more power efficient).
So, customers want their devices to be faster, lighter, thinner, smaller, waterproof, more power efficient and doesn’t cost an arm and a leg to repair.
