It also means thicker device or less battery life.

the case of the second display takes space which could be used for a higher capacity battery and the second display need additional power from the battery.

    

  Is that thicker than switch handheld device?

As for the battery thing, I think that  I can't  confute your claimings...

  

Are you serious? This thing is a 3D-model, they can make it as thick or thin as they want without factoring in battery capacity, power drain, performance, weight or cooling.
