Fitbit Premium appears to cost $80/year, but side-loading an app so you can play with data yourself is free. On the other hand, the Apple Watch requires buying a macbook ($1000 one time) + a $100/year annual subscription for ad-hoc distribution to run your own app on your watch and play with data. I assume the majority of hacker news users who buy a smart watch are going to end up writing a few simple apps/widgets/whatever for themselves, so it seems to me like, even if you do buy the optional fitbit premium subscription, you'll end up paying less per year than for an apple watch. I'm quite hesitant of smart-watches that lock writing and running my own simple widgets behind a subscription.
