What Do You Hate The Most About Your Mac?

Now that my complete and total infatuation with my Mac has worn off and shifted into delight and love, I’m starting to explore the weaknesses of the Mac for not other reason than I’m trying to figure out where the real rough edges are.

So – if you are a Mac user, I’m very interested in the things you don’t like about the Mac, especially the things you hate.  I offered up the Address Book as a burnt offering the other day.  Anything else out there that blows?
