This is about the future: When people are sick of Android unreliability, and other OSes offer a much better user experience – because they dont run on a Virtual Machine. Actually that has already happened, but Android keeps ahead because of functionality and apps.
But, Android will never overcome the disadvantages of its Virtual Machine. Android will keep itself alive because of its apps. For a while, those apps are the only advantage Android will continue to have over other OSes.
Other OSes find themselves trying to catch up with Android apps. Despite having a more stable and better performing platform, Android shows that people most appreciate being able to do a lot of stuff. At the moment Windows is trying to fill its own app store, and there are rumors of a project to run android apps on windows phone. Amazon has already adjusted its own branch of Android so that it can run Android apps.
After about 1 or 2 years, Android will clearly start losing its app advantage. From that point, its days are numbered. Windows and Tizen are working hard to increase their functionality. Android’s party is coming to an end.
