Horace Dediu on the possibility of the Apple Watch standing on its own one day:

I think this too is inevitable. The technology trajectories are easy enough to plot. Apple has invested enormously in the silicon that goes inside the Watch and has taken it to new levels of connectivity with LTE, 85% faster WiFi, and a 70% faster processor; all with 50% better power efficiency.

These enable independent voice entry, Siri everywhere, Find My Friends, Maps, music streaming. These breakthroughs are only possible with a new W2 processor which is more powerful than the first iPhone processors.

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.

So not only is the Series 3 Watch more powerful than the original iPhone but it is also poetically capable of the same tentpole jobs. But it’s not just a miniature iPhone. It has a new, completely orthogonal attack on non-consumption and market creation: fitness and health. This is a key point. The iPhone was born a phone but grew up to be something completely unprecedented, unforeseen by its creators and, frankly, undescribable in the language of 2007.

The Watch was born a timepiece but it is traversing through the early iPhone and pulling in a new direction all of its own. The fact that we are talking about “Resting Rate”, “Arrhythmia” and “Atrial fibrillation” at a timekeeping launch event indicates that new behaviors will follow and so will the language we’ll use to describe this child-like product once it grows up.
