Great invention for this fast kind of life. They have almost every feature that person needs for doing business, excersing or having fun. In my firm I see colleagues who have this smart watches do not need to chech theirs smart phones for mails or any type of notifications. They only look at their watches and information is there. This little bastards are usefull for training purposes also for measuring heart rate and giving informations for workout. In my opinion they will replace old classic watches in near future, but they need to adjust prices for market, because they are expensive and not so many people can afford them.
