It may seem like the modern smartphone has been around forever, but the iPhone hit the market a mere five years ago. In half a decade it became harder to find someone without a smartphone than it is to find someone sporting a iPhone or Android. Widespread smartphone adoption happened so quickly, in fact, that it outpaced PC adoption at the height of the personal computer boom of the 1980s AND Internet adoption in the ’90s. From CNet:

Research firm Flurry Analytics today announced that iOS and Android adoption is ten times greater than PC adoption at that technology’s rapid-growth phase in the 1980s. The mobile platforms have amassed users twice as quickly as the Web during its go-go period in the 1990s, and three times faster than recent social networks. …

“Year-over-year, Flurry calculates that net active devices in the U.S. grew by approximately 30 million, while China saw more than 100 million new active devices enter the market,” Flurry said today in a statement. “At this rate, China’s active installed base could overtake the United States as early as the 2012 Holiday season.” …

Flurry didn’t break out the popularity of the platforms in its own study. However, the company did share some other interesting insights, including that Singapore leads the world with 92 percent Android and iOS penetration within its borders. Hong Kong and Sweden followed with 87 percent and 86 percent penetration, respectively. The U.S. came in fifth place with 78 percent penetration.
