Chrome OS will fail — not by going down in flames, but by being quietly folded into Android. In fact, Android is already absorbing Chrome OS as we speak. R.I.P. Chrome OS; you were too far ahead of your time.
I agree with Chris Hoffman’s prediction, I simply do not see the point of developing 2 mobile operating systems at the same time. Of course there are differences in conception and purpose between Chrome OS and Android, but not enough to keep them as distinct products. Again an example of fragmentation of focus by concentrating on too many directions at the same time. Just pick one of them (most likely Android) and make it work on all mobile platforms.
