According to Nielsen's latest data on U.S. smartphone share, smartphone powered by Android operating systems with 29% share is pulling ahead of RIM's Blackberry 27% and Apple iOS 27%.
Nielsen says that because RIM and Apple create and sell their own smartphones with their OS, these companies are actually in a better position in the three-way race (in terms of device manfuacturers). Because Google licenses its OS to device manufacturers, the Android ecosystem is more fragmented.
In terms of the break down of Android OS, 12% of Android smartphone owners have an HTC device, with Motorola following behind with 10% share. Samsung comes in 3rd with 5%.
Nielsen also said that a higher percentage Android users fall into a younger age group (8%) vs RIM (4%) and Apple (4%).
