It is interesting how different perception was 20 years ago.<p>My cousin had a Sinclair PC200 back then, that IIRC was Amstrad&#x27;s poor attempt to get in to the PC market. That was a 8086 based PC with CGA card, and it came with DOS 3-something and GEOS (don&#x27;t remember the version).<p>My cousin had a mouse and all, quite uncommon back then, and we tried and experimented with GEOS quite a lot, but we couldn&#x27;t see the point really.<p>Perhaps was a limitation of the monitor and&#x2F;or the CGA card (it didn&#x27;t look to good in the high resolution mode of the CGA, with a very poor refresh rate) or the limitations of the 740 KB floppies, but the CLI that DOS provided was definitely better!
