Also on Fi - I use hangouts for everything. On desktop hangouts has my SMS and Fi phone number available for voice calls. On the run, hangouts is on my phone for SMS, and I can use my phone as normal for calling people. It's far and away the best experience I've had with a Google product outside of search/gmail. They really need to look at what the Fi folks are doing, because it is truly excellent.
