NYT Bits Blog:
According to Kevin Restivo, an analyst at IDC, the countries where Windows Phone shipments exceeded those of iPhone during the fourth quarter were: Argentina, India, Poland, Russia, South Africa and Ukraine. A seventh “country” where Windows Phone shipments beat iPhone is actually a group of smaller countries, including Croatia, that IDC lumps together in a category called “rest of central and eastern Europe.”
So Gruber’s question is answered.
The paragraph I found interesting was the final one:
Mr. Restivo said that Windows Phone tends to thrive in parts of the world that are traditional strongholds for Nokia, Microsoft’s flagship handset partner. In many of those markets, there is less demand for the iPhone because of its high cost and the lack of carrier subsidies.
