When do you use autopilots?

Do you use autopilots on short trips (along the lines of an hour or
so)? Do you use autopilots systematically on IFR flights?

Is it bad form to use the autopilot for a 25-minute flight? I've
tried KPAE-KTIW under IFR both by hand and with autopilot, and
autopilot is a breeze in any weather whereas flying by hand is
troublesome even without any wind or turbulence. I try to fly by
hand, but the lure of the autopilot is strong sometimes and I use it
to get some rest.

So how often do you use autopilots in real life? And to what extent
to you prefer to use them?
