As 2011 draws to a close, it’s time to take a look at the year that’s been. In this post I’m going to take a tour of the highs and lows of Android’s year.

It's been a very mixed year for Android. Without a doubt it's been a great year in terms of sales of devices and activations, with over 700,000 devices now being activated daily. However, Android has seen malware attacks and also been the focus of patent infringement lawsuits and patent deals that bring in millions each year for Microsoft. Also, former Apple CEO Steve Jobs called Android a stolen product.

All in all, 2011 was the year of the Android OS ... only problem is that fragmentation of the platform is so bad (because most users never get the chance to upgrade) that you can't really tell which version of Android is the winner.
