Nice! But it won’t be a full fledged phone replacement for most people because of using the phone (such as for GPS/music/podcasts) in the car where there is no wifi access.
True, I haven’t thought of that. It would work perfectly for light use. You would have to forgo social media when not in range of wifi though (such as while on the bus) and phone calls without wifi (assuming you will use Google Voice, TextNow, or something similar) though. Some people are willing to make that sacrifice, but I think the majority of people will see this as a major turn-off.
