If this runs a version of iOS, we can't access the code that is running in it, we can't open a terminal, we can't use our programing language of choice. We can't use the actual device for building anything hacker related by itself. We can make apps for it using an actual PC made for building, but only if it…

Even that 1986 6th grade hacker…
This "you can build and directly deploy an app to a limited number of devices if you're on the developer program and have a mac, therefore you can 'hack iOS all you want'" meme is borderline dishonest.
Also, the fact that you "fail to see the fascination" is of little significance to those who do want to develop on-device. You don't get to make "you can hack iOS all you want" work by restricting what people are allowed to want.
