For some, it’s because there’s less competition on WP7, or because they’re most familiar with Microsoft’s tools, or because they simply don’t care for the way iOS and Android operate. Microsoft is fighting to exploit those beliefs and recruit the developers who hold them; the company's success or failure at doing so may mean the success or failure of the Windows Phone 7 platform.

With just over 30,000 apps available for WP7, and only 2 percent of the United States smartphone market, Microsoft is a very small fish in a very competitive pond. But it is growing: According to Microsoft’s stats, Windows Phone 7 gained some 5000 apps in the past two months. Sure, that’s nothing next to the half-million apps on iOS, and the 200,000 you can find on Android, but WP7’s growing apps store shows that some developers think the platform is worth the time and effort.
