why the Apple II was still kept around for that long is kind of a mystery to me.
It's not games. Maybe educational customers?
Maybe next to no migration path for business users? I had an uncle who ran a veterinarian clinic off of Appleworks and several floppies worth of data for god knows how long.
"Works for me" is a powerful force, and they'd probably squeezed all the costs out of the Apple II line.

There was a very strong following, especially in the educational market. I remember seeing schools purchasing labs of IIGS's as late as the early 1990's.
Basically, the apple ][ was the cash cow that kept Apple afloat for years while they tried to sell 68k macs. Apple basically tried to kill the II for a decade but wasn't successful enough to just cut off the customer base that was crying for new models.
