apple is building its own OS Just saw this post, and to be clear most other examples of companies making their own smartphone OS have been completely failures. Blackberry had their moment, but they are done. All of the various in-house OS' at the other makers are sputtering or dead. Apple is the anomaly here, and when people use Apple as the example of anything to follow, it ignores the enormous counterexamples. Apple succeeded with the iPhone because of the iPod and iTunes. Those early sales -- the ones that protected it from being end-of-lifed -- were almost entirely to people who had a big knowledge and investment with the iTunes ecosystem. Microsoft has nothing like that.
