So i would probably only wear it on the weekend and after work...
Would you still buy one if you couldnt wear it all the time?
Absolutely! I'm not interested in wearing the watch all the time. I'm interested in it mainly for sporting & fitness activities, which occur after work.
The fact it has to be charged every day, makes this a perfect use scenario -- it's always charged and ready for me to use.
The only thing holding it back from being the perfect device for me is that it doesn't have an IPX8 water-resistance rating so that I can use it in the water.
The optimal use scenario for me is for surfing. With the Watch I don't have to worry about keys, or money, since the watch will lock and unlock my house, and Pay allows me to pay for coffee, or food when I'm at the beach. It also will allow me to track the tides, and give me the time in case I have to cut my session short.
I could care less about notifications, though I appreciate there might be a situation in which that could come in handy -- work is not such an environment. I'm only concerned about fitness tracking when I'm working out, not at work as there are plenty of other ways to make sure I remain active during the day than a taptic reminder on my wrist. And taking phone calls on my wrist is the last thing I ever want to do, especially at work. Otherwise, there's nothing else at work that my iPhone can't do just as well.
