I don't want it unless it has an exposed CLI without jail breaking.
In fact there are Android apps that do this. It's harder on iOS because you don't get fork(), but if someone wanted to try super hard, you could make all the apps run as threads within the same process.
If you want a root shell without jailbreaking, that's almost contradictory.
Hell, in Android you can even run Debian without rooting: https://play.google.com/store/apps/details?id=com.cuntubuntu...
I was disappointed that my MacBook didn't have a coffee machine built into it. In reality, it would have been a silly thing to ask for, or assert "I don't want a MacBook unless it has a coffee machine in it" as if they would bend their entire product range to suit me.
Why is this so difficult.
