Mild exaggeration. They're usually 2 inches from what I recall. If you're doing a lot of light switches or even a few it's still a lot of turns with your hand, or you know 2-3 seconds with a drill. But for 2 gang box, that's 4 2" screws + 4 decorative screws. So 5 minutes is not really an exaggeration to take all that out, about the same to put it all back in. And when you take into consideration how it's better to just shove a ton of wires into the box (as contractors do) instead of leaving the wires too short, the mechanical advantage of the drill doing the work allowing you to align the screw with minimal and accurate force instead of doing accurate alignment while cranking hard with a screwdriver... yes it's a big win. And then you get to flat head decorative screws, I find it way easier to use a drill on those as it is easier to not scratch the paint off of the screws, which bothers me.
