In defense of Unix 10 years ago
@7 - is that so ? I just gave up installing F# developer tools in Windows last night after two hours, 3 general install methods (check the F# foundation site) and some 6+ installer packages (some of which wanted to eat 8GB of diskspace). - And yes, my copy of windows is reasonably modern (8.1) and legal.
Contrast that with Ubuntu, where installing F# took all of 5 minutes, with one command, 200MB and I had a full IDE and F# support.
The one concession I'll make is the one you yourself seem ignorant of - ease of use pertains to your expertise with the system. If you grew up on Windows, you may get its idiosyncrasies.
