Lets wait for it to get into the hands of real world users. It's a brand new product and with that comes fiddling with it all day. Every single one of my iPhones that I've owned as well as my Android phones have NEVER made it through a full day when I first buy them (the first week even). Lets see how it goes with real world use and then complain if it's that terrible.
I'm doubtful about it because its a watch. Shouldn't be using that much power where one person has to change it twice in one day. But yeah we'll see how it fares in the coming weeks, although not sounding good right now. Looks gorgeous though
