Australia, U.K., Sweden, Norway, Saudi Arabia and UAE each have more than 50 percent of their population on smartphones.
An additional seven countries—U.S., New Zealand, Denmark, Ireland, Netherlands, Spain and Switzerland—now have greater than 40 percent smartphone penetration. In the United States, Google research indicates.
By way of comparison, Nielsen recently pointed out that U.S. smart phone penetration had surpassed the game console as the "most adopted" newer technology in the home environment.
In terms of growth rates, nothing compared to the adoption of tablets, up about 400 percent over the last 12 months, Nielsen data suggests.
Qualitatively, the smart phone adoption wave has key implications for any business that currently assumes people will use a PC when interacting with Internet content and information. increasingly, that is not a very good assumption.
