It has been though going for Windows Phone 7 to gain traction since it launched a year and a half ago. Being late with the new operating system, Windows Phone 7 also lagged in terms of the apps available.
But Windows Phone is big in China. In the two months since Windows Phone has been on sale in China, it has captured 7% of the smartphone market share, going past Apple's iPhone at 6%. Android is still the king in China, with Android being far ahead with a 68% market share. But with Windows phone going from 0% to 7% in just two months, nothing is impossible.
A small victory in China is significant, as China is now the worlds largest smartphone market.
Another problem for Windows Phone has been having less available apps compared to Android and iOS. But Windows Phone now has over 90,000 apps available in the Windows Market place, and I think a maturing market it realizing that having 400,000 to 500,000 apps in the market place is meaningless when the average Google Android and Apple smartphone user has all of 41 apps installed on their phone with the top 50 apps in the market command 58% of all use.
