Is no one interested in a more stable SolidWorks experience??
I suspect we'd all be more interested in a more stable SolidWorks experience, just on Windows. If they're going to re-write that much code to remove Windows-dependency they might as well re-write the Windows version and get that as stable as it could be (ZTG and all!).
Among other issues would be "which Linux?" I suspect there'd be more fiddling necessary to get it working smoothly / stably on Ubuntu / Red Hat / Mint / whatever. Then support becomes a nightmare because every reseller needs to know the ins and outs of every Linux variant. Unless you only support specific instances/versions, which will inevitably be the "wrong" version for many people.
I'd imagine an OSX version would be more likely - fewer OS variants, fewer hardware variants, and fewer people in the forums asking about running SW in Parallels / Bootcamp, heh.
