Pull up your pants, your paternalistic attitudes are showing. Who are you to decide what they spend their money on in the poorer countries, don't you think they are able to prioritize their spending?
Mobile phones are extremely popular in developing countries, and assist in not just personal communication but in development itself via mobile banking, information services etc.

This should also give you some perspective when you doom Nokia saying Apple has them beat. How many trendy iPhones are you going to see among the world's poorer people?
