I believe that is similar for me, in addition it would be good to have a fallback for GPS if no satellite can be reached (thick clouds, forest, inside buildings, …).
Edit: I probably need the location only for navigation (atm I do have the problem that I sometimes have reached my destination before a satellite was found…) and location information in photos. Haven’t gotten into mapping yet.
I hope I can trust Mozilla (and that the date transmitted is rather anonymous). Otherwise I totally agree to you and thus use the google free phone.
