Nelson survey: Half of U.S. mobile phone users use smart phones
As of the end of February this year, the proportion of smart phones in all mobile phones rose to 49.7% from 36% in the same period last year. In the past three months, smart phones accounted for two-thirds of mobile phone sales.
Of the smartphones sold in the last three months, the Android market share is as high as 48%, iOS is followed by 43%, the BlackBerry share is 5%, and the "other platform" is only 3%. Forty-eight percent of smartphone users use Android smartphones, 32.1% use iPhones, 11.6% use BlackBerrys, and 8% use “other†smartphones.
Given that many smart phones currently sell for less than $100, ordinary mobile phones may eventually follow the path of DVD players. Of course, there will always be some users who are unwilling to purchase data services, especially those who have multiple devices.
