Thanks for the link! From that data, it looks like Windows Phone is close to parity with iOS when you look at the EU market.
Only if you can't read a chart. Even in the EU chart, iOS is about 2x WP.
The world IS larger than just the US, you know.
The world is also bigger than the EU. If you look at global numbers, WP looks flatlined compared to iOS.
Also check India [statista.com] where Windows Phone has a larger market share than iOS. It's actually succeeding quite well outside the US...
Can't see the chart but I can only assume you are ignoring the fact that Lumia phones are on huge discount in India and that Apple doesn't do any real discounting. Again for global numbers, it appears Android is dominant, iOS is present, and Windows is barely above RIM and Symbian. That is not success.
