I've gone through this with my wife, and finally just asked her. She wants the same thing I think the price difference between this model and the other similar ones were +/- $20. I showed her all of them and this is the one she chose, so that's what I'm going to get her too.
As far as the phone, my understanding is it will work with any Android phone, so your Moto G should be fine. It will be a nicer phone than what she has now.
