How Important Has App Ecosystem Become?

It is a given these days that a robust applications environment is essential for an operating system or device to attain huge success in the consumer market. What is less clear is whether any device manufacturer "needs" its own app ecosystem, or can succeed by leveraging the OS ecosystem. 

A somewhat related question is whether other participants in the mobile business "need" their own ecosystems to enhance their specific roles within the ecosystem. The value and feasibility of mobile service provider app stores provides an example. 

Samsung also is a case in point. Up to this point, Samsung has achieved significant success in the smart phone business by leveraging Android and the Android apps ecosystem. One might argue that nothing has changed, just because of the Apple patent infringement win. 

Google Play arguably provides equal benefit to every manufacturer of Android handsets. And, at least so far, it is hard to see that Google's ownership of Motorola has bestowed any particular advantage on Motorola, or any particular disadvantage to any Android licensee. 

Microsoft does face a problem, though, in building a critical mass of developers and apps for Windows Mobile. It's just a classic "chicken and egg" problem. Developers don't have lots of incentive to develop for an ecosystem with negligible numbers of users. Users don't have unusual incentives to buy a device using an OS that has significantly fewer apps available. 

That doesn't mean Microsoft can't get it done, but the end user device installed base will matter.
