Nielsen: Android still growing in the US.

Android grew from 39% to 43% market share for Q3-2011, taking market share away from RIM and Windows, while iOS holding its own at 28% for two quarters.  No surprise that Android is taking market share away from RIM and Microsoft.  Android phones have the highest download speeds, as they're the only 4G phones, and are the fastest HSPA+ phones out there -- a fact that won't change until some time next year.
