PNP blogger, Franklin Elieh, recently learned about Chico-based Computers for Classrooms, a non-profit agency that seeks to deliver inexpensive computers or laptops into the hands of those living on fixed incomes that may not be able to afford purchasing a full system. They can provide a robust refurbished device starting at $100 with a one-year software and hardware guarantee. You can view their current inventory and price list. Though they're based in Chico, they can arrange for shipping at a relatively nominal fee.
