If you've read the biography, you probably know that Steve jobs initially said no to the idea of the iPhone having an app store. He later came around. I personally like the new Apple TV UI. The previous version had pull down type menus, which can make it difficult to find stuff as your content inventory grows. The icon like app interface they've adopted now, similar to ios, is something more people are accustomed to and something they can keep adding to, "folders" could become "channels" etc.
