You say a third-worlder in a lean-to shack might not spend their hard-earned money on iPhone apps. I lived in Rio de Janeiro in the early seventies as a small kid. My parents were missionaries and we'd visit very poor areas of town often, and some times we'd go to the famous "favelas" (slums) where people live in improvised lean-to-shack housing. People in the favelas didn't have much, but almost every corrugated-metal/wood/cardboard shack had a TV antenna. These days people might not spend the money on the apps but they'll spend it on an iPhone or a smart-phone. They'll find a cheap way to get the apps they really need. In Brazil people love technology, especially when it helps them connect with others. I don't think it's much different in other third-world places.
