Google's Android is quickly becoming the favored mobile operating system not only in the United States but on a global scale, as Canalys recently reported that Android captured 35 percent of the worldwide market in the first quarter of 2011.

According to the report, this is the second consecutive quarter that Android has led the market. Overall, the quarter saw 101 million smartphones ship, with 35.7 million being devices based on the Android OS.

For the first time since the third quarter of 2007, the Asia-Pacific region became the largest smartphone market in the world, surpassing Europe, the Middle East and Africa. This is due to strong demand in China, South Korea and India, each of which posted triple-digit growth, Canalys noted.

While Google has led the global market, Nokia is still the favored mobile phone developer in APAC, accounting for 53 percent of its overall market. This may prove beneficial to Microsoft and its Windows Phone 7, as earlier this year, the companies announced a partnership to include the mobile OS on future Nokia phones.

Though WP7 got off to a shaky start, many industry observers are now predicting monumental growth for the OS. According to a recent IDC study, WP7 will become the world's No. 2 mobile OS by 2015.
