I think you're exactly right here. It's not that people don't think of it as a health device, and that probably helps sales via justification. But most people I know who have it, when asked, have no F-ing clue what about their health they're tracking.

And yeah, if you do care that much (amateur or pro athlete training) there's no way the A-watch is the primary device for you. Garmin is the king of the hill in that market.
