This comparison is apt: the Watch is effectively stealing usage from the iPhone. At first it took alerts, timekeeping, and basic messaging away. Now it’s taking basic phone calls and music and maybe maps.

It’s fitting therefore to remember how the iPhone was launched; as a tentpole troika: A wide-screen iPod, an Internet Communicator and a Phone. Today the new Watch is a small-screen iPod, an Internet Communicator and a Phone.
