Just a thought.... I have seen some presentations of the Surface Duo and some of the scenarios of spanning apps over the two screens seem really useful to me! And I would love to have the option to use the same type of spanning on my regular Surface Pro. What do you think? Would it be nice to be able to set up a set of apps that you can always open in dual mode? Or be able to swipe information from one side of the screen to the other half?
