Yes I could run most any MS Windows software on my iMac. But running it is not the point. Closed source software like this is just a "magic black box" and you can't see how it works.
The point is like this: Why build a GPSDO when you can simply buy a Thunderbolt, apply power and go? The same answers apply to software. You want to learn the issues involved, you want to modify it or use it in a different environment. Especially the last part, different environment. I'd like to have my GPSDO draw performance plots and some diagnostics on a little cell phone size LCD screen.
