10/GUI is doing the rounds and is summed up as multi-touch with advanced window and application interaction. I like it though it is a demo and has some issues. I like windows stacking horizontally but I still want the speed and simplicity of alt-tabbing between two windows. The “near field” representation of where your fingers lie on the touch surface is very good, it has always been a problem with touch systems that do not overlay the display. I’m not convinced that a drafting layout is bad for your neck or has obscuring problems. I did drafting in school and loved standing up and swiping my hands and tools over a large, inclined draft table. We obscure what we interact with in everyday life, we have ways of coping that separating the display and touch-screen do not need to solve.
