I agree. But if one doesn't define a "general purpose computer" as being a piece of hardware, then all kinds of different conclusions can be drawn.
If what Amelius pointed out here: https://news.ycombinator.com/item?id=32116822 is true, i.e. the documentation is junk. Then, IMHO, Apple is no longer trying to sell "a good piece of hardware"; because they're not documenting its operation.
And, in reality, I find this to be true... what Apple really sells is "an experience".
Whether it's a good or bad experience is likely in the eye of the beholder.
