For example my auntie calling me in tears because windows "had performed an illegal operation" (verbatim error message text) and she was terrified she was going to prison.
Many non-dev folks around me have resolved windows errors by typing the error message or code into google - if they are spesific and well written, they enable you to do that!
This is just one example that I vividly recall. The simplest of operation downloading of an update, only apple can make it as big a nightmare as it was. Now they do a lot of things fabulously but when the fail they just fall on their face and ignore it or they would fail where I can't even imagine how to fail this bad.
The latest blunder (again download), my iPhone lost it's wifi after a fall and wow! behold you can't download an update over cellular. Apple will make you save your money by not using your expensive cellular data after all it's so much more expensive than your $800 phone.
