It’s a nice machine, but I find it uninspired, a bit like the C128, which instead of improving the VIC II, added a VDP with garish RGBi colors. Both look like they tried to check all boxes and, in the end, made computers unable to follow on their immediate ancestors legacy. Both disappointed me because they could be so much more.
I like both my IIgs and C128D. They largely serve the function of running everything the earlier machines in their line run, but neither is very exciting for bringing new capabilities to the line. Both suffered from developers being hamstrung by supporting the older machines because the new machines didn't have major adoption. The new features felt to be mostly unused.
At the very least, the two video chips could support overlaying on composite and analog RGB output (because nice colours). The way it ended up was just silly.
