Legend has it that after AT&T stomped all over their fun little research OS by turning it into a popular product and all the tedious concerns like "backward compatibility" that entails, the creators of Unix got together and said, 'right, we'll make a new OS and give it the least marketable name we can imagine so that it will never be taken away from us and ossified'. Although I've never used Plan 9 myself (I don't think I've ever owned hardware it would boot on), I am impressed by the features I've read about, and I wish it had become more popular... but on the other hand, I'm quite happy with the chording-free and keyboard-friendly UIs I have available.
