GEOS (originally developped by <A HREF="http://www.geoworks.com/"
  >Geoworks</A>, then taken over by New Deal and now by <A HREF="http://www.breadbox.com/"
  >Breadbox Computer Company LLC</A>) is some very fine _(OO) *(OS) for various kinds of computers (including PCs), that comes with a _(GUI) and various office applications. One of its most notable aspects is that it isn't a resource pig: it already provided a _(GUI) to 8-bit computers (_(Commodore) 64/128, _(Apple) ][), and multitasks fine even on 8088 computers (but takes advantage of _(Intel) 32-bit mode when available). It has consequently been ported successfully to various hand-held platforms.
