Is it really an affordable situation with the current pricing of the RPI to setup a computer cafe for the kids who don't have access to the computers and internet ?
Access to Internet, thankfully and recently, has become super affordable by my own standards to give away. I have a 100Mbps fiber from Airtel (I have US/Europe calls all the time) at around USD 15 (INR 900) / month. I could easily get another for the cafe.
Rent for a small garage would be about USD 35 / month. Electricity would not cross USD 50 / month.
