Surprisingly, the US doesn't have the highest per-capita Android ownership out there - at last count that goes to the UK, where one out of every four men, women and children owns an Android smartphone. But the US is catching up quickly. ComScore reports that Android accounted fora staggering 50.1% of smartphone owners in the United Stats as of February, a statistic that hasn't been matched since Blackberry and Palm OS were duking it out. ComScore's numbers show a 3.2% overall market share increase in the four-month period ending in February. Rival statistical firm NPD reached the same conclusion back in December.
