Indeed, really bad there is no mac flight simulator! I think a sim is essential if you're flying helicopter. Two years ago I bought a PC laptop with good 3D card *only* to run a simulator. At that time this was the top of the line machine as the standard laptops did not have 3D cards and would not run my sim at 60Hz. It has a large HD which is deemed to remain nearly empty! The only other application I tried was a macintosh emulator (so that I would have a fallback if my mac fails) but unfortunately mac emulators only support up to OS8.1.....
