Four billion

Global health

A few months ago, a malaria guy showed me the $20 dumb Nokia phones he buys in a Geneva convenience store and then gives out to trainees who then use it to collect data via SMS text messages. ARM says that the US$20 smart phone (read: Android with an ARM chip) will arrive this year. At stake: how to get the next four billion people online. Source: ARM says $20 smartphones coming this year, shows off 64-bit Cortex-A53 and A57 performance. Photo: Fr3d.org/Flickr
