shrug I use it on a daily basis, over top of Linux, mostly. I've used Wily/Acme-SAC/Acme as my programming and OS interface for the past 10 years (2003-), after 11 years of Emacs (1992-2003). Both systems are completely reprogrammable, and Inferno has the advantage of being an actual OS (as opposed to a kitchen sink). I recommend it because it's a good way to get the feeling that you know the whole system, which you seem to be interested in, like the early home computers. I think the major three OSes are a little too big and bloated to get the same feel. Also, since it's a VM, you can take it around to other machines, and share it with other people, without changing the base OS they use.
