Re: 53.6 million tonnes of e-waste
We do not need a new Iphone model every year.
No, but Apple needs us to think we do. (Ditto for Google, Sammy, etc.)
My strategy:
* Buy last year's not-top-of-the-line model, when the price drops after the new one ships.
* Use it until it's out of support and/or can no longer do useful things.
* Repeat, typically in about 5 years (for an iPhone, at least).
Device cost of ownership works out to about $120-150 per year. Even a 6-year-old iPhone in decent shape still has some value on the secondary market, so it doesn't go the the landfill right away when I'm done with it.
Of course, this only works if you don't give a damn about having the newest shiniest.
