I think mj2c is right in that they are going to be upgrades to the existing OS like Apple does instead of an entirely new OS. However, I wonder what the enterprise is going to think of this. I understand the idea of keeping up with technology which moves at the speed of sound, but this seems like they are moving away what people are comfortable with. And large companies constantly having to do these upgrades? Not gonna happen.
