Reviews of the Apple Watch Series 3 — which includes GPS and optional cellular connectivity for placing phone calls on the go — are out.
The consensus seems to be that it's convenient to have a watch with a connection when you don't have a cell phone, but that the battery life is pretty bad when you're using it in those situations. Most reviewers don't see the cellular model as a worthy upgrade.
