I really became interested in the Linux / UNIX world during my college program. If I want this stuff to be a part of my career direction, I wondered if I should look into Plan 9 more. So far, I have installed the basic system and just explored their Rio window manager a little bit. Before I bother tackling this, I wondered if this is even widely used outside of a few University science research teams. I guess it's main advantage is parallel processing or distributed computing.
