Its C-inspired programming language is also pretty primitive. It's actually very beautiful. It's just so damned simple. Despite Plan 9's huge codebase, if you open an arbitrary source file, chances are you can read and grok it in one sitting. It's shocking especially if you're used to the needlessly complicated modern codebases of today (particularly ones that copiously use GLib, D-Bus, etc. on Linux), but once the initial shock dies down, it's a breath of fresh air.
