If you've ever thrown out a single smartphone, by weight you've created more ewaste than a lifetime of those rings. There's more ewaste in a single AA battery, surely you must complain about those in every comment thread they're mentioned?
I get OP's point though -- yes, all smartphones do tend to end up as e-waste in the end, but would you buy a smartphone if it couldn't ever be charged?
If, every time you powered on the phone, you knew you were draining from its finite battery life? I would probably think twice before doing any kind of software updates at least!
