I’m sorry who other than Microsoft wants Metro UI? Nobody wanted it when it was called Zune, nobody wanted it when it was called Kin, nobody wants it now it’s called Windows Phone 7. The only Metro-ish interface they have left is the 360 dashboard and that was shoe horned onto an already successful device.
Microsoft spent 10 years trying to smash the square block (Desktop Windows) into the round hole (tablets). Now it wants to spend another 10 (?) trying to smash the round block (Metro) into the square hole (Desktop PCs).
It’s not confusing to have different interfaces for different forms of something. Cars, Boats, Trains and Planes are all transport, but do not require one size doesn’t fit all controls.
