I used Plan 9 continuously for one summer, a while ago, when I was in high school. It's a nice environment, but certainly not something that could be used for day-to-day computing. I still needed another computer for almost anything that did not involve coding. I don't remember if that was before or after they open sourced it, but I distinctly remember poking around the source code during another summer. It's a pleasure to read it. They ignored a lot of received wisdom and the result is an elegant, if unpolished and occasionally buggy, system. IMHO it would have made much more of an impact if it had not been kept on a leash by Bell Labs. I still use Acme occasionally and some of the bunch of scripts I use are in rc. Acme is a beautiful editor that doesn't get in my way much, but the mouse-only interface is fairly clunky and I don't have the time and energy to keep my own patches over it for sane (ahem, emacs) bindings. I use it, occasionally, as a distraction when working on a more boring project, or when I just have to write long streams of text that don't require much jumping around.
