And interestingly enough to what some are complaining about the screen saver, on OS X the screen saver, desktop picture, and sound theme are bastard children with near zero updates in a decade. Straight up. But they're still customizable for people who want to.

What's wrong with that? Just provide a standard install location and let those that want to utilize it do so.

As an avid Mac OS X/Linux/Ubuntu user, I really truly don't get the direction Canonical is heading with Unity.
