I switched to Key2 (currently on third...too many oopsies) after burning through two Priv, but I still know at least one serious Priv holdout locally (SWE wife of a EE friend) for strictly keypad reasons. The S8 did somewhat interest me due to its snap-on accessory keypad, but I couldn't get over paying a flagship pricetag and then some for a half-assed keypad that explicitly nerfs 30% of display real estate out the gate.
If OnwardMobility's eventual offering has a proper Blackberry-class keypad, it'll be an instant in for +2, and friend's wife will def be in for at least one as well.
