The latest numbers are available for Google's mobile OS, Android. We've seen Android 4.4 KitKat increase its grip on the market, jumping just 0.3% for the month.
Jelly Bean increased by a decent margin, increasing from November's numbers of 54.5%, to December's 59.1%. Gingerbread continues to slide, losing around 3% since the last time we saw these numbers. As for Ice Cream Sandwich, we're seeing 16.9% still, but this will continue to erode as people upgrade, and new devices are pushed onto the market.
Over 75% of Android devices are now running Android 4.x, which is great for developers with apps that require Android 4.x and above.
