Ok that sounds reasonable, that these surprisingly low cost phones, cannot last that long. At the same time, shipping phones to far away places where there is a "shortage" of phones, and selling them there, is going to be more profitable, per shipment, than shipping water to that same place. And one needs just a few shipments of phones, for everyone to have a phone. One ships just 0.1 kg phone per person, once. Compared to 10 or 100 kg water per person and day. With that in mind, I'm thinking phones will continue to be prevalent, in comparison to water, in areas where there's a drought.
