I think I did.

The argument here was "well, if Apple can assume that users are going to learn a list of shortcuts, why can't Microsoft."

The answer is because the keyboard shortcuts on OS X are actually shortcuts, not required for using the operating system. The gestures Microsoft has incorporated in to Win8 are the only way of doing things, whereas I can do things a few different ways on OS X.

Let's stick with closing an app. Apparently the gesture is swiping from top to bottom on Win8. On OS X, I can do that by clicking the red button (arguably the most intuitive method), by going to the File menu, or the keyboard shortcut, Command-W.
