I have a few questions. The most important one is, what happens when you forget your phone and go for a walk? Does it have to be close to the phone at all times? Compared to a Fitbit (their wristband was irritating my wrist, so that is why I am looking at an Apple Watch), how does the tracking hold up? Are there any plans for a newer one? Will it be worth it to wait? I am thinking of getting the standard watch with the Milanese Loop. Is it worth it getting the bigger one? Thanks!
