The introduction of the M7 last year seemed to be a step in this direction. It's also the only major use I can see for wearables such as watches. If there are planning to release a watch health monitoring would be the main selling point for me. I don't need a device on my wrist letting me know I have a new text message/email/notification. This would be a much better use of that technology.
You know, I thought the same thing until I got a Pebble to do some development on. Turns out, I really like getting notifications on my wrist. Lets me know if it's actually something I need to get my phone out for.
Also, it's easier to dismiss calls if I'm in a place where I can't/don't want to take a call.
The question is, how far will Apple go down this path. Will they kill any developer with a health and fitness tracking app, or just provide the tools to make our apps better?
Until reading this article, I was excited for the possibilities of an iWatch for my apps. Now I'm a little bit scared of being crushed by Apple.
