Can we please stop using the term "Wife Acceptance Factor"/WAF when it comes to technology and/or hobbies? It's sexist AF.
It assumes it's always the wife who's technically less literate, who has (implicitly unfair) ux demands & who's in the way of the husband's fun.
If the problem is something being too nerdy for the other people in your household, maybe use "household acceptance factor"/HAF?
If the problem is a lack of communication about purchases or hobbies - learn to communicate FFS.
