Jared is right, XP ain't for the eye candy folks. Because we all know in the real world...
1) Planes start, with engines running, on the runway
2) There are never any other planes flying or taxiing near you
3) ATC are idiots
4) the world is flat
5) airports are deserted, with no terminals, jetways, vehicles...
6) pilots NEVER fly by using landmarks like roads, tracks and waterways on the ground for navigation
These are all "features" of X-Plane...even into the latest release (disappointment), XPlane 6.0.
But hey, for us Mac users, XP is the only choice until MS Flight Sim is ported to Apple (happening in 2002, hopefully)
