So please explain to me: what the hell does the input method (keyboard, mouse, touchscreen) have to do with the low-level security properties of a system? If anything, the switch to tablets and thus more ubiquitous computing makes security an extremely critical issue (see the many discussions about permission systems, application sandboxes, malware leaking personal information etc...). It will become even more pressing in the future, if you think about devices that are controlled by thought (EEG etc...).

Think of a java applet in a browser catching all your keyboard input for instance; the general idea is that secure system must guarantee that user input goes where intended and only there.

Sure. Of course. But my point is, how is that different for touch screen-based input or a real keyboard? The grandparent poster seems to think that in the post-pc era, security problems disappear in puffs of colored icons and magical gestures.
