Google’s mobile Android operating system is celebrating it’s 5th birthday.
Google tells us the total number Androids hit a half billion back in mid-September, around the same time Google Chairman Eric Schmidt was quoted as saying there were 1.3 million new activations each day. Doing some quick math on the Android calculator app, we get just over 570 million total activations up to the current day. That’s almost two Android devices per U.S. citizen, and quickly approaching one for every 10 people on Earth.
