> For Apple Watch, all application code lives on the phone and every interaction on the watch requires a round trip to the phone and back.

IIRC this is just for now, and they're going to have native apps soon, but the SDK for that isn't ready yet.

I wonder if the (current) Apple Watch approach is better battery-life wise, given that it avoids any data syncing and does any and all heavy processing on the iPhone rather than the watch.
