I agree. The really sad thing is as well as improving on many other aspects of Plan 9, Inferno also makes the UI much more sane and comprehensible, by accepting that by the mid-1990s a lot of standardisation had happened in GUI design, and incorporating that. Inferno is, for me, much easier and saner to use. Inferno is to Plan 9 as Plan 9 is to UNIX: taking the ideas further, fixing the rough edges and making it more versatile and more general. But Inferno is even more obscure and forgotten than Plan 9. Some 15Y ago I was able to find an ISO image of x86-32 Inferno and boot it in a VM. Not today. :-(
