[citation][nom]Caffeinecarl[/nom]So Android gains from 45.4% to 51.2%, which is a gain of 5.8%, while Windows Phone goes from 2.7% to 4.1% which is a total gain of 1.4%...So in other words, Android gains marketshare of almost 1.5x all of Windows Phone's installed base, but yet the news is that Windows Phone is doing so well?BIASED MUCH?!There is a clear leader in the mobile OS race, and it's Android![/citation]
Your math ability is pretty indicative of the American education system.
Android going from 45.4 to 51.2 is certainly a gain, but only one of around 8.7%, while its around 65% increase for WP. In the UK WP share more than doubled and in Italy its an almost 300% increase.
However, the percentages really shouldn't be looked at too hard as android tablets are counted as phones which skews things somewhat, and many people including myself have multiple devices from the different groupings represented by these new numbers.
Android is a useful OS, but its so damn ugly and fragmented it really shouldn't be counted as a single system any more. Also, its free to license, unlike all of the other OSes. It would be interesting to see how the pie would be divided if royalties had to be paid by handset manufacturers like with every other mobile OS.
