Quite some years ago, we brought the #OLPC AKA the 100$ laptop to Rwanda [1]. A surprising thing happened. The laptops were often without battery power in the morning. A thing that wasn’t anticipated. It had two reasons. One was the keyboard LED. It was used by the parents to have a light at home. The other was a bigger surprise. The parents used the mesh networking to discuss market prices for their produce. Fascinating. 1/3
