Nielsen: US Smartphone Ownership Now 50%

Although the Pew Internet Project was the first to report that at least 50% of US mobile phone owners had smartphones, Nielsen waited until today to make the same statement: "Almost half (49.7%) of U.S. mobile subscribers now own smartphones, as of February 2012." This compares with 36% a year ago. 

However if smartphone ownership is segmented by age and income, the numbers are much higher than 50% for some categories.

Nielsen says that Android's share of smartphones in February was 48% while Apple's was 32%. However among 90-day recent buyers, the numbers are much closer (48% vs. 43%), reflecting the popularity of the iPhone 4S and its availability from mulitple carriers.

All others, including RIM and Microsoft are under 20% collectively. However the trend is away from these platforms among recent buyers. Microsoft is hoping to reverse that with the expensive and high-profile launch of the Lumia 800 at AT&T next month.
