The inexpensive smart phone is the primary device for many of the world's less affluent. Cellphones are the primary communications device, pop a tower in a remote village with solar charging capacity and you don't have to cut paths through the wilds for copper or fiber lines. It's cheaper this way. They're also not paying what we pay for the premium devices, but cheap Chinese cellphones.
This should be welcomed, as they can now be connected to services, education, and society as never before. Here in the US a homeless person can have access to a phone for jobs, family etc. communication - this is a good thing and would not necessitate cutting-edge technology.
Over 300 million people in India have no access to a power grid at all, there is still a lot of progress to be made. It will be distributed infrastructure, little islands of cell coverage and solar charged batteries. That alone will be a revolution compared with lighting houses with crude kerosene lamps, and the particulate pollution they create. The same situation exists in a lot of Africa, Asia and South America. Stay tuned, the world is changing.
And banking. That has been revolutionary for small industry. That people no longer have to stuff cash in their homes means a lot. Like Asia, using the cell account as a bank or having access to a "traditional" bank in electronic form means a lot.
