Finally the prediction that one day the Android OS would overtake iPhone OS has come true!

Still, it is more of a testament to the appeal of the iPhone, that it has taken dozens of devices by featuring the same Android Operating System to overtake the iPhone OS – which is only offered on three smartphone devices, the iPhone 2G, the iPhone 3G, and the iPhone 3GS.

RIM still maintains its position though, and with a share of 36% it is clear ahead of both Android and iPhone OS. Android is now second in place with a share of 28%, while the iPhone OS lags at 21%.

While the news isn’ unexpected – in fact it was always a matter of when rather than if – the fact that it has happened so fast is impressive. It has been less than 2 years since the release of the first version of Android, which was used on very few devices. It is only with the release of Android 1.5 that the OS started appearing on devices.

In this short history, Android has gone from a few HTC phones to over two dozen manufacturers and with tablet and even netbook devices. There is no stopping Android now!
