I, too, agree that the sim can't replace the "real thing". I have a great deal of trouble finding the runway myself, but can at least make very nice landings where ever I end up. That is the dis-advantage of 2D.
OTOH, the sim is a great way for us newbies to learn orientation and control in the air, especially when the aricraft is headed in our general direction. It is also a fun place to spend a rainy Saturday or Sunday afternoon. Crash all the planes you want/can and keep on going!
