No tin box here. Probably too late for that since I bought my FS2004 in January 2004 (that's when I started fightsimming; I had a little bit of real world soaring experience). FS2004 is living on on its second PC now since two years, the old one having given up the ghost.
In fact I installed three versions of FS2004 on this computer: CalClassic scenery (my absolute favorite), Golden Wings 3 and FS2004 (scenery around 2003 incl. Ultimate Terrain USA, Canada/Alaska, Europe and RealNZ scenery, plus various add-on of course).
No plans to go FSX despite MJ's beautiful goodies, though one never knows.
Cheers,
Maarten
