Third-quarter estimates from IDC regarding the smartphone market are now out, and they show that Google's (NASDAQ:GOOGL) Android operating system now ships on a whopping three-quarters of all smartphones sold in the world. That's a phenomenal figure for a mobile operating system platform that's only four years young. Its next closest competitor was Apple (NASDAQ:AAPL) with "just" a 15% market share -- a fifth of Big G's. Research In Motion (NASDAQ:BBRY) saw its market share fall below 5%, as it awaits the launch of BlackBerry 10 next year. Microsoft (NASDAQ:MSFT) is also transitioning to its new Windows Phone 8 platform, banking on hardware partners like Samsung, Nokia (NYSE:NOK), and HTC to boost its share. Still, with 90% of devices now running either iOS or Android, there's not a lot left for the rest of the players.
