When my mother says she needs a new phone it means I need a new phone and I pass down my 2 year old phone down to her and she passes her 5 year old phone to some family relative in rural Nepal and that family member passes on their 9+ year old phone to the next person.
And when my dad says he needs a new phone it means my wife usually buys a new one and passes her 4 year old phone to my dad who then somehow finds someone who wants his 9+ year phone to use.
Pretty soon I will have to factor in my two growing daughters into this upgrade cycle.
