I completely agree and disagree with that. It completely depends on the situation.

For example (and to bring it closer to home) If someone sits down and says I want to watch ( TV, BD, Netflix....) it should be intuitive and a single press. A small number of stuff that are used daily should be easy access and intuitive through the GUI.

On the other hand if I add all the controls on all the devices it would make the GUI extremely heavy so those would need to be buried somewhere so the important stuff is easy and intuitive. Furthermore I don't want people to mess with settings and stuff, but I want to be able to access them on my system, so on my controllers full access to device buttons are behind a PIN purposefully created not to be intuitive and someone needs to have instructions (pin) to access it.
