Google informs me that there are 20 to 50 million tons of electronic waste per year. 400 million phones, each phone weighs less than half a pound, so let's say 200 million pounds per year, divide by 2000, that means 100 thousand tons of electronic waste saved.

Less than a percentage point of reduction of purely electronic waste. This is what I mean by "almost all waste claims fall apart when examined."

It's a bit unfair to measure by weight, because mobile phones are light. One television, monitor or desktop computer can weigh more than 10kg, but may not have the same impact on the environment as 10kg/125g = 80 mobile phones. And besides, why stop with mobile phones? We're doing the same with TVs, now they're smart, but 3 year old apps don't work anymore, so: next!

Well, that's why I asked you to quantify things. If you have reason to believe that mobile phones punch above their weight in terms of e-waste, tell me exactly why, and how much. Does that mean that saving 400 million mobile phones per year goes from saving 0.6% of e-waste to 0.8% of e-waste?

And I'm not defending the practice of throwing out TVs or computers or anything else after 2 years, just phones.
