Apples were in computer stores, the Ace, perhaps, not so much. Having an actual use case to run both Apple and CP/M software was rare. It was also complicated. If you were an end user running CP/M on your Apple, it very well just stayed that way. Hard enough to wrangle a single computer system, much less two completely different ones.
