This is my case exactly. What else can it possibly do? It tells me the time, wiggles my wrist for all my appts, reminders, messages, slacks, and even answer phone calls. Oh and it tracks my pathetic exercise and motion as a bonus.

I can now leave my iPhone6 on my desk at work, and on a table and home and never have to carry it around with me (at those locations). It does exactly what a >Watch< should do. It's not a computer it's a 2nd screen for my phone.
