I have a fondness as NetBSD was the first Unix I ever installed (circa fall of '94)... for about 4 hours or so, then I had to restore my Amiga4000 back to AmigaOS for work on Monday :).

I set up a NetBSD VM (on my Macbook) that I had intended to use but there was just enough friction/lack of pkgsrc knowledge that I never made the leap.
