One OS to Rule Them All (IOS)

I could not disagree more, although many of the features of IOS and OS X are converging, the OS's are not. Apple is taking the best concepts from each OS and cross pollinating them into the other, while at the same unifying features that already do the same thing. This will make both OS's better and the experience of moving between the two better, while still maintaining the distinct advantages that both platforms offer.

As for his predictions that everything will be everywhere, sure why not? All the built-in apple IOS apps cover basic functionality you would want on any computer, and same goes for their services.

However, the input methods for OS X and IOS will always be different which requires different work flows and methodologies. Mouse/Keyboard and Touch interfaces are not interchangeable, and never will be.
