For the thousands of young people in emerging Asia wanting to break into the apps market, perhaps an opportunity? But the hundreds of thousands of apps that run on Apple and Android devices will not work on phones like the Lumia 900 that use Microsoft’s Windows Phone software. And many developers are reluctant to funnel time and money into an app for what is still a small and unproved market. So Microsoft has come up with incentives, like plying developers with free phones and the promise of prime spots in its app store and in Windows Phone advertising. It is even going so far as to finance the development of Windows Phone versions of well-known apps — something that app makers estimate would otherwise cost them anywhere from $60,000 to $600,000, depending on the complexity of the app.
