I see a lot of evidence that Google is trying to ditch Android and make a Chrome for mobile operation system based on their Chrome OS project.
One of recent moves that makes me think it's really serious it their momentum around Chrome Apps for mobile [1]. The main reason is licensing, Google is giving away it's work for free to Amazon and others who fork Android and give back nothing. Chrome OS on other hand is licensed against this. Google can control everything from end to end.
Moving to a web based ecosystem gives Google ability to deliver their services on almost any platform very easy. They already started their push on framed web apps in both iOS and Android.
To all of this, add Dart and web components that Google is pushing on it.To me it's obvious that Google will ditch Android some day and move fast enough to leave everyone behind with an old operation system on their hand.
What do you think? Is there enough reasons for Google to do this?
