I agree that it's not a problem if you hide stuff which you do not need for average use to achieve greater ease of use, that is what Ubuntu and other user friendly distros are also doing.
However, Apple's philosophy seems to be at least in recent times especially with their mobile Operating Systems to not to only hide the "nuts and bolts" but to disable any access to them which goes to such extremes that you cannot even install the software YOU want on the iPhone and iPad but only which Apple allows you to through their app store. I bet that if the Mac were invented now this would be the case there to. There are other examples how Apple cripples also OSX, though, like that you cannot even install OSX on ~99.9% of computers.
This is where I think Ubuntu is the perfect compromise. It is extremely user friendly by default but leaves you all the freedoms to tinker with it as much as you want, that's superior to Apple's philosophy to offer you only ease of use which it can only achieve with extreme restrictions.
