Well cost can always be an issue but the 950 is better than the 930 in so many ways its hard to imagine many people would take a 930 if offered either.
I mean SD card (up to 2TB), replaceable backs (huge appearance advantage), faster, higher res screen, Continuum if you ever need it, replaceable battery, Windows Hello. Now someone can say they would never want some of those but things do change and they have a value if only as insurance against having to replace a 930 later.
