I tried the demo for a few weeks. About gave up on XP11 till I figured out how to get rid of the haze. I was not impressed with the demo.
I've played sims since Flight Sim 2.1 on a 3.5" floppy. Loved FS9, but that damned money pit FSX burned me out with the constant tweaking and gave up on the hobby about 4 years ago. I had P3Dv2.5 and never even installed it.... A few months ago I finally installed P3Dv2.5, and realized I really do miss the hobby and purchased P3Dv4.
A few days ago my wife surprised me with Aerofly FS2 for my birthday, tried it for 70 minutes and was bored to tears, so I refunded it and got XP11... My wife hasn't seen anything but the back of my head since I got XP11. I can't leave it alone :)
