Android: A visual history

Google’s Android operating system has undergone a pretty incredible metamorphosis since it debuted on the T-Mobile G1, which celebrates its fifth anniversary this week. Half a decade might seem like a long time, but on the scale of the PC’s growth, it’s a blink of an eye. You could make a pretty convincing argument that no consumer technology in history has evolved as quickly as the smartphone, and Android has been at the very center of that evolution.
