I've used netbsd mainly for fun. I run it on my SparcStations. I also run Gentoo, Redhat 5.2 and OpenBSD on them. OpenBSD is alot nicer out of the box acutally but NetBSD tends to have a bit more hardware supported and has SMP for 32 bit Sparc so it sorta depends on the particular box I want to run it on.
YOU'RE EITHER FUCK INSANE, CHILDISH and LOVE BDSM. Seriously, see the psychiatrist before you harm yourself further and after that for the love of the would, delete BSD and gentoo and install Fedora, Ubuntu or Mint.
