At Betalogue, Pierre Igot offers a demolition job 
on iCal’s user interface.
He points out a number of problems in design and operation with its text fields, contextual menus and information drawer.
I’ve been using iCal for two years now (since switching) and already I’ve become harden to these problems — I unconsciously work around them, I think it’s normal, I don’t see them at all anymore, if I ever did. But Pierre does.
