I have a friend that is telling me that OS X 10.7 will be the last release of Mac OS X, from then on it will be the iOS ported to the computers to take over from Mac OS, it will like Mac iOS v11.0
I don't necessarily agree with him on this, I think there will be a 10.8 and 10.9, but who knows.
I have friends too. Some work for Apple and even THEY don't have a clue. They really don't.
