Where is it all going?
Android became the most used mobile OS in recent years and has plenty of apps now. Chrome OS however is not as successful and based on webapps. With a rumored touchscreen chromebook Android and Chrome OS will be more similar, I guess. Furthermore Google Glasses are coming probably next year, but nobody knows anything about their OS. Likewise, it is difficult to say how the Google TV interface will develope. I personally think Google Now will play an important role in the future of their devices.
So what do you expect from Google? Do you think they are going to combine the OSs? What is Android 5.0 going to look like?
