Don't dulplicate desktop stuff to mobile device (Score 2, Interesting)

We keep duplicating desktop User Interface (UI) metaphor to mobile device, i.e., copy GUI, web stuffs to PDA, cellular phone and now, watch. Come on, it wouldn't work well. We need an innovative UI for mobile device. I don't know what it will be. But I do know it wouldn't be GUI stuff. Probably audio based UI.
