There were a lot of IIGS's, schools purchased them in bulk. Plus, they were the machine to upgrade to, so a lot of die hard apple ][ users ended up on the GS.

The IIc+ is actually the last apple II created and wasn't particularly popular because it "split" the market by being a 8 bit computer which couldn't run the newer IIGS's/16-bit software. OTOH, it was clocked faster than the IIGS. In a way it was just apple's response to the laser 128+, which was a much better IIc. The cynical take was that apple didn't want to create another product that would eat into its mac sales like a 32-bit apple II, or much faster IIGS would have done. So they backed the feature set down. The IIGS continued on as the choice apple product long after the IIc+ came out because people were just buying transwarps/etc, hard drives, etc to create a more advanced IIGS.
