Great question. I am using the ASIAir Pro exclusively for imaging now instead of the laptop. I started with APT, moved to N.I.N.A (which is AMAZING btw). I still use my Polemaster for alignment (then take the laptop back inside), but the ASIAir pro has a polar alignment feature as well. I just haven't messed with it. From everything being set up inside, to getting everything setup outside, aligned, and imaging now takes 20 - 30min total. The guiding in ASIAir seems to be a copy of PHD2, so it's straight forward. Accuracy wise, the platesolving, guiding, imaging, etc. has been great. I dont think I'm willing to go back to a laptop. The ASIAir/iPad is just too easy.
I do need to setup the wifi range extender I picked up, because that IS an issue with the ASIAir (wifi range). Not bad, just not great either.
*The BIGGEST thing that helped speed up my setup was cable management. I'll get some photos tonight, but everything stays attached to the scope (cables, cameras, etc) so I just have to slide it on and plug in the cables. I now have no issues with meridian flips (also automated with ASIAir - can be turned off) and tangled cables.
