> how do I close an application again, on iOS, Android and Windows8? Christ, yeah, I still remember before Microsoft attempted to patch Windows 8 into a somewhat less unusable OS, I had opened one of those Metro apps to see what it was like. And then exactly that, I sat there for probably at least ten minutes not knowing how to close it, again. Eventually, through pure chance, I moved the mouse to the top of the screen, and that then unhid what was essentially a window titlebar with a close-button on it. But no indicator for it, no tutorial shouting at me how to do it, there was simply no reason for me to ever move my mouse to the top of the screen.
