Well yeah, but don’t you think this is exceptionally hard with a touch screen?

Didn’t microsoft try to do this in Windows 8 with little icons in the corners? The problem is that little icons provide only marginally more information, if at all, than the existence of the corner of the screen.

It’s a very hard problem and Apple works on it. They have abandoned previous standards on discoverability because of the inherent limitations of a touch interface on a small screen.

Sacrificing discoverability for usability is the right choice.

I think one issue is that some UI conventions have not been settled on, so I often have to look up how to do something on iOS.

The most recent example of this was “shake to undo.” After looking this up, not only did I learn how to undo typing, I also learned why I would occasionally get these inexplicable warning windows asking if I wanted to undo!
