No, that's the cool bit: it's like a cell phone on your wrist!
The 4g connection is pretty good, and I think the call quality is pretty decent. Battery can only handle maybe an hour and a half of call per day (between charges), but I'm not too chatty, so it works great for me.
Right? It really violates the Law of Least Astonishment. I think part of the idea is that the phone serves as a close hub to get push notifications from, since it doesn't retrieve my mail without the phone. Which honestly I'm starting to think I preferred (you really start to notice how much nonsense heads your way when the notifier is on your wrist).
Sounds more like a bluetooth headset that you wear on your wrist
