They had the tablets in Bob Bilby and the lack of tablets in Road Trip, there was also Bluey trying to steal some time to play games during Family Meeting so they’re never painted in a particularly good light.
I dunno, they seem like not a “techie” family if I’m honest, Bandit seems like he would rather be playing footy or watching the cricket and the girls would rather be at the park or making up some imaginative games.
