If I didn’t use Microsoft Flight sim, I’d not need any windows at all.

Look into Flight Gear.

Binaries/Source available for:

Windows
Linux
Mac OS X
Solaris (sparc/x86)
sgi
FreeBSD

Perhaps not as polished as FS (yet) but getting there.

I did look into it. I don’t like it. I am studying X-Plane though. It may be good enough to replace FSX, which I already own. Bah, I might have to dual boot Vista and have them both.
