Mac OS X peccadillos
There’s usually little sport in pointing out UI flaws in an OS, but Mac OS X is well-enough designed that it’s actually fun, like catching an erudite friend confusing a tense or saying “kinda.”
Here are several examples. Good times!
Terminology

Huh? Remapping record identifiers? What the heck?

So, saving a movie is an operation. Good to know.
Controls

Menu buttons look like a button, but act like a menu. Fine in concept, but the execution—slapping a normal menu against a normal button—is startlingly crude. The menu should really emerge more organically from the button.
The sign in dialog contains a useful little flag button that lets you choose a language, but it shouldn’t be in the window title bar.
And lastly, there are some good aspects to the new Help menu, but the way the menu grabs focus and causes selection highlighting to flash in the front window is not among them.
A sometimes fun thing is to look for humor in Apple messages. For example, go to Apple’s homepage and type virus into the search field then wait for the popup result.
But you do know you can get TinkerTools (http://www.bresink.com/osx/TinkerTool.html) that allows you to let the Help Window not be in the front!

…or putting punctuation outside quotation marks?
Thanks, instig8r. Period moved inside quotation marks.
