Sorry if I wasn't clear ... I do write Haskell on Linux.
I meant that F# would be enough to entice me away from Linux and overcome my activation barrier against using Windows. As long as it wasn't glorified C# with a thin functional wrapper, and it was a focus on real functional techniques, it would be highly interesting for me.
I do not have much of any F# experience but I write C# in my day job. I've heard nothing but good things about F#, including from people similar to you with a functional background incl. Haskell.
