I'll go back to playing Shufflepuck Cafe..... in color.@ NJRoadfan - it was about the apps, not the OS, especially back in 1986 before all wound up being developed for Windows.
The Apple IIgs out of the box was compatible with 8-bit Apple II programs, so long time favorites like VisiCalc and Appleworks were still in use (the latter saw updates into the late 90s-early 00s). There were IIgs specific apps like Appleworks GS. In terms of content creation, most of the 16-bit era programs like Deluxe Paint were ported to the system. Plus you got stuff like Music Construction Set on the audio side.
