Anybody remember PC/GEOS (or its "little brother" GEOS for the commodore 64), its now about 25 years old, but guess what its still around (but barely), see this article, the death of GEOS.
quote from the article:
The current copyright holders (Breadbox Computer Corporation) believe the future is to position PC/GEOS as an educationally focused OS for low powered portable computers particularly for emerging computer markets in second and third world countries, not unlike the OLCP educational computers. To this end Breadbox Computer Company has provided free utilities to assist in the creation of educational content.
The great thing about (PC)GEOS has always been that it could do so much with so little.
Wouldn"t it be great if GEOS would make a re-appearance on the R-PI?
yes, its written for x86, and almost nobody supports it these days, but other than that it seems the R-PI and GEOS are a close fit!
