After last month’s report ranked Android as the top smartphone platform in the United States, the operating system’s share has continued to grow. Google’s mobile OS now accounts for 33 percent of all Smartphones in the US, or one third of all mobile handsets accessing the airwaves. Pretty impressive for a platform that barely held any presence in the market less than two years ago. Remember, most analysts predict within the next three or four years Android will grow to account for as much as 50 percent of the market. How about that.
