From the top of that, the 3 reasons why Skyrim's UI is less than efficient:
1. Not making good use of screen real estate
2. Requiring too many user actions to reach information
3. Putting crucial information below the fold
Really though, that picture has way too many good points to list. Many i hadn't even thought of, like where the lists start. *shakes head*
That pic makes one thing obvious. The UI isn't just bad because it's designed for consoles, it's bad because of poor design decisions.
However, at least #3 is a direct consequence of the UI being designed for consoles. Consoles don't have a mouse, so you're required to scroll anyway. It doesn't matter whether the list starts at the top of the screen or in the middle, because you'll be pressing down on your gamepad anyway to scroll down in the list.
I guess PC users are the winners in the end, because someone will no doubt completely redesign the UI, fixing all the issues and optimizing it for a mouse+keyboard. Console users will be stuck forever with a poorly designed UI.
