Having done this, I prefer the Apple products:
1. The keyboards have very little travel so it is considerably less effort to type on them then to type on a standard keyboard.
2. The Magic Mouse has a large multitouch surface on it that enables gestures that I have a hard time going without. Also, it fits my hand. YMMV.
but, still; matter of taste. there will always be lovers and haters, and you're certainly welcome to prefer one over the other.
Sure, they make mistakes. Probably quite a number of them. Nobody is perfect. But I'd say their mistakes are insignificant compared to their achievements.
Plus, sometimes they're not mistakes; they just don't target power users. A single-button mouse is an example of that. And to some extent choosing aesthetics over usability can be an example of this too. A non-tech person might prefer a pretty mouse and keyboard because he only checks his email occasionally and he's not a great typist anyways.
(mind, I do realize Apple often did not 'invent' these things. They just were clever enough to polish these things up and productize them, which rather bafflingly few companies did before them)

Their keyboards and mice particularly showcase this: they look pretty and sleek, but try using them all day, and then try using a regular keyboard and mouse. They weren't thinking about the human who has to use it, they were thinking of appeal and looks.
You're not wrong about the approachability of IOS; that's no accident, and required a good deal of thought and attention. But I think whenever there is a tie, and they can either improve the aesthetics or improve the usability, they lean towards the former, because it's sexier and will sell.
