What they can do is correct way faster, with better accuracy and with less momentum shift than mount-motor corrections. This makes them very useful for slightly windy conditions when you couldn't otherwise image, and for where your mount is at the limits of its capability. Both situations are common in our hobby, and AO gives a real benefit.

With crappy seeing however, I just go back inside and catch up on IIS

AO works best when seeing is good, and when seeing is good, that is when you really want to be imaging, so it is a win-win to me.
Good summary Peter, should have just asked you in the first place
