Well, obviously there are tons of apps that have diluted leather's distinctiveness (and leather is but one example), but the argument for a garish, non-functional skin is still as I outlined above.
Also, I didn't mean to imply that leather in itself teaches you how an app works. However, once you've used an app with a distinct skin, the next time you launch that app the skin, as a sort of visual touchstone, will help you remember how you used it in the past, etc.
