I'd rather take a FaceTime video call than try to surf the Internet on that tiny screen. It's good to see who you're talking to even if it's a small image. It's not as though you will have to do it. And it's not as though you would have to do it with everyone. That's the great thing about choice.
So if my daughter is halfway across the world, as she is sometimes, I'd love to see her when she calls.
But the WiFi triangulation feature is good. When you're running, or even just walking, it will be better able to keep track without needing the phone, which is a major complaint today. No doubt, there will be a number of other feature updates as well.
But let's remember that this is just a rumor now.
