.06% of Android Users on the Latest Version

Android fragmentation is a serious problem for Android users. It's one of the bigger reasons for Android's lack of big app developers. It's also the reason few people run the latest version of Android. Many Android devices are outdated at launch, and even those that aren't don't expect them to be running the latest version of the OS a year after release. Compare that to iOS 5, which still works on the 2+ year old 3GS.

Ice Cream Sandwich, the latest version of Android, is currently on .06% of devices. That's 6 in 10,000 people. Most Android users are actually using a version of Android 2, which is two generations old. In comparison, one month after iOS 5 was released, it was on 40% of iPhones, and even available on the much older iPhone 3GS. Thanks to Android fragmentation, you're guaranteed to be behind the technology curve, either as soon as you buy the device, or soon after.
