Finnish digital technology analyst Horace Dediu made this cool chart showing how much slower smartphone adoption has gone in Finland than in other Nordic countries:
Interestingly, this isn't because Finland is a backward or benighted place. It's almost certainly the opposite — Finland is home to Nokia, which was the dominant mobile phone maker of the early 21st century but has struggled to make a touchscreen device that people enjoy. But as the rest of the world started to turn to iPhones and Android-powered devices, the deep ties between Finland and Nokia encouraged people to stick with feature phones even as other countries were moving on.
