I also think the simplicity of tablet/phone UI's is not applicable. There's always a trade off in design; you cannot make one UI good for everything. As it stands, the desktop UI is a bit too complicated for simple app/game/media consumption. But similarly the tablet/phone UI is way too simple for most desktop applications. Tablet applications literally do less so they don't need as complex of a UI. You can't take that simplicity and apply to more complex applications.
