@Dave 126 You beat me to it.
I was just about to post that link! It is indeed a very interesting pont. It is clear that Mountain View have decided that if the OEMs and the carriers will not work with them as far as this is oncerned then Google has to work round them. The more obvious this becomes the less the producers and the carriers are going to like it given that they all have an interest in not allowing as many upgrades as the given device would support. I wonder if any of them are considering "doing. an Amazon" forking the OS and going it alone?
