The cursor changes when you get to resizing corners and edges, so I don't suffer from the problem pointed out in the original article. However, I do find something annoying: sometimes when I'm resizing (or maybe dragging) a window, it gets expanded to fill the whole screen.

I think that kind of behaviour ought to be controlled by the green dot at the top-left of windows, not by some particular mouse movements.

There was a time when the changes to the mac UI were quite good, or at least not annoying. Sometimes it seems as though they are changing stuff just to change stuff.
