Google's monthly Android distribution charts may be the most visual piece of evidence that the mobile OS is riddled with fragmentation, but at least Gingerbread has clearly become the dominant player -- and it continues to build momentum at a healthy pace (for now, at least). As always, Google reviewed which devices accessed the Android Market during a 14-day period of time in the month of December, and found that over 55 percent of those units were running a version of Android 2.3, a ten percent turbo boost from October and an increase of seventeen percent over three months. Froyo devices -- many of which are likely older phones or tablets sentenced to a upgrade-less future -- numbered over 30 percent, and Honeycomb still amounts to a meager 3.3 percent. Cupcake and ICS are tied for last place, but we expect ICS to climb rapidly as soon as it's, y'know, officially available on more devices.
