Google's purchase of Motorola Mobility. I said at the time that they have made a mistake IMHO and I have not changed my mind. They offered their rivals an opportunity they could not dream of to compete with them on their own turf! As for the PC/Mobile analogy, I believe the mobile market has yet to mature and there is still a window of opportunity for competing OSes.
Is this also partly an attempt by the old guard, represented by LiMo and Linux Foundations to curtail the success of Google, by providing an alternative that can take market share.
For a long time the telecommunicaions giants fought to keep Wintel out of phones.
It just seems that in the case of Google the IT and communications giants may be trying to shut the stable door after the horse is off and running and half-way across the next county.
The reason all this is happening is because companies need to distinguish themselves. Following along doesn't show you're a leader. So what you do is provide distractions with slightly different concepts.....just enough to keep everybody confused and scrambling and thinking you're the next greatest thing. If it fails, then just invent something else.
