I loathe hot corners; every day or so I accidentally lock the screen on my work macbook because when I fling the mouse pointer out of the way of what I'm looking at it hits a corner.

I also loathe full-screen menus. Screens are big, and having the entire contents of my screen be replaced with an information-heavy overlay is a non-trivial perceptual context switch which instantly causes me to lose my place in what I was doing. You underestimate how cheap a right-click menu selection can be; press, drag a small distance down, let go. And if the app's designed properly you can right click anywhere.

(Which, to be honest, most apps aren't. I grew up on RISC OS, which was driven entirely by context menus, and did this stuff right --- each app was a single context target. Modern apps have different contexts for every tiny UI element. Web browsers are particularly bad; I can't count the number of time I've done 'Open in new tab' rather than 'Back' because the mouse just happened to be on a link rather than a text area.)

My point is: one size doesn't fit all.
