I just got this plane last week, and am having a blast with it as well.  I've been practicing short IFR flights between Edinburgh and Glasgow Prestwick.  I have all systems working properly at this point, now enjoying fine tuning my approach and landings.  Really love all the eye candy and the ACE and the freight loading and other animations.  Really top notch.

You do have to learn about some quirks, but once you do, it's really fun.  I especially like hand flying this bird.  It is really nice.
