I didn't realise you could just push the scope around once set up though, does that not ruin the star alignment?

No the skywatcher GOTO is a closed loop system with independent encoders as well as the ones on the servo motors. Once you have done initial alignment the scope knows where it is pointing at all times. The difference from the servocat system is that the Skywatcher has slip clutches that allow manual pushing that seems to work quite well.
I found pointing accuracy adequate but clearly the more you calibrate it to work in the area of sky you are working the better it points.
A hybrid solution might be to use the drag n'track side of the stock drive for tracking and an Argo for accurate aid finding objects and all the joys of its searcheable database.
