For me it is, because i can buy another smartwatch or fitness tracker for half the price that can do the same thing. If it doesnt track your sleep, why does it even matter to wear it at night or whats the use case for having 2-3 day battery. If that wasnt a big deal samsung could have given us one day battery, and made the device cheaper. No the watch doesnt tell you to go to bed at a certain time which I dont think it should. The gear fit doesnt have the same functionality as the s2, for example you cannot reply to messages from the gear fit, but then again you cant track sleep from s2. I want something complete and not half baked. If their own application that they made for the device offers sleep tracking, why not build that into the device itself. Overall I like the s2 mainly because of its rotating bezel but I would like a complete product, personally.
