Those two things atleast aren't necesary on *nix. The lowest common denominator *nix filesystem - ext2 - takes care of itself quite well in terms of defragging, and it's successors (ext3, reiserfs, xfs, jfs...) do it even better. And there are *nix boxes out there that have uptime measured in years. I'm fairly sure *nix is usually better at RAM allocation, too (although I don't know much about that).
