I'm not looking to buy one anytime soon until theres actually more useful apps on them, I have had the original samsung gear and the samsung gear 2 both were waste of money as they have very limited functions so not worth the high price tag ( nevertheless they still look cool and they actually bring a lot of attention ;p).
However because a lot of companies are making smart watches now like apple,lg,sony , motorola , samsung, huawei and asus .... they should be more choice in apps in another year or 2, so I'm not writing them off totally yet
