The Apple IIc was a compact version of the Apple II that eschewed internal expansion slots in favor of having the popular expansion options already built in, and saving cost and weight. Apple expected it to sell a hundred thousand units per month, but it actually sold only a hundred thousand per year. Writers then and since, have attributed the lack of sales to the market really wanting expandability.
That's a summary of the historical facts, detailed further on Wikipedia: https://en.wikipedia.org/wiki/Apple_IIc
I'm curious about reasons. Because it seems to me that specialists and enthusiasts, the sort of people likely to be writing about computers, are also likely to care much more about expandability than the average customer; as long as the machine has the options you want, such as eighty columns, the average customer just looking for something that gets the job done, should be happy with that.
If I were considering the purchase of such a machine (admittedly a counterfactual, as teenage me couldn't have afforded a significant fraction of the price of an Apple computer), my reasoning for eschewing the Apple IIc would have been the small screen.
So Apple was of the opinion was that the IIc should sell well, the typical enthusiast writer was of the opinion that it should sell badly because of the lack of internal expansion slots, and I'm of the opinion that it should sell badly because of the small screen. And the historical outcome was that it sold badly, for whatever reason.
Is there any evidence regarding why the IIc sold badly? Customer surveys? First-hand accounts from people who sold computers at the time? Anything better than a guess at the reasons?
