I'd recommend FreeBSD . I've found it to be the most approachable of the freely available unices. Installation is straightforward, and the ports tree resolves dependencies to in a manner to similar to the package based linux distros. If you're interested in linux, consider having a look at Debian . I've found it to be the most sustainable linux distro as far as being able to do continuous upgrades without backing up and starting over. I've also had a better experience with debian's package management system (apt) than with SuSE or Mandrake, particularly when running combinations of package and source based apps. An easy way to evaluate Debian is to check out Knoppix  or Gnoppix . These are live-cd based Debian variants that use the KDE and Gnome desktop environments respectively. You can boot into a live system from a cd without touching your hard drive. You can even install from one of these cds and use it as the basis for your Debian system.
