I think this is a the first act from apple entering into active lifestyle market for the endurance/outback/mountain and outgoing folks.

It is definitely not for me this year, it does not have the battery life I need during an excursion and there is no possibility of charge on the go (like good old Garmin watches that you can charge while using during an activity).

But in few years it will advance the same way apple watch has advanced :-).
