When you look at the smartphone market today compared to just a few years ago, you'd be surprised at just how different it is. Today's smartphones are slowly taking on more features of PCs than phones – and none more so than the recent release of Windows Phone 8.

You could put this down to hardware, with high end phones such as the Samsung Galaxy S3 or HTC One X both powered by quad core processors, but the software is also continually evolving to support it.
