@CapitalB @genmaicha plan9 is great as long as you do plan9 stuff. not a failure of plan9, the world just moved in a different direction. bsds are.. ok? i like netbsd because the community doesn't have the elitist crap of open and freebsd so that's where i likely will end up. i'd love hurd to work on more real hardware (and it's getting there because of netbsd ;) haiku also is interesting. oberon as well.
no shortage in interesting systems. just get a cheap android for the control grid apps.
