The PCjr had the promise of "runs some PC software", so if Dad needs to finish his spreadsheet from the office in an emergency, he can barge the kids off the PCjr for the night.
If it had been something different to the point of total incompatibility, why not buy the kids a cheaper Atari 800XL or C64 for games and "educational software" instead?
You can also argue that the PCjr's unique features did survive a bit longer, in the form of the Tandy 1000 series.
