Survey: Smartphone purchases on the rise

During the past three months, more consumers purchased a smartphone than a traditional cellphone, says a survey conducted by Nielsen.
From March through May of this year, 55% of consumers who participated in the survey say they bought a smartphone. That's up from 34% in 2010.
Overall, 38% of U.S. consumers own a smartphone.
Android remains the dominant operating system, finds Nielsen, with a 38% share. The Google smartphone OS is followed by Apple's iOS at 27% and BlackBerry at 21%.
However, Nielsen says Apple has shown the most growth over the last three months among recent smartphone buyers, up 7%.
