As a PC user, I must say I was appalled when I first saw the UI for this game. It's gotten easier to use and there are actually some things I like about it (although still some things I don't like). Looting is so easy with this interface. I can loot things in less than a second; even corpses where I don't take everything. Also, selling things to vendors is so much faster than in Oblivion.
On a side note, has anyone else noticed that the wasd keys don't work when you activate a bookshelf?
