What's the difference between apple-touch-icon and apple-touch-icon-precomposed?
With apple-touch-icon vs. apple-touch-icon-precomposed, the difference is that apple-touch-icon is a square bland rendition of your logo or icon, without any shadows, rounded corners or glass effect applied - iOS will do that for you, in case it want to (looking at you iOS 7) - while apple-touch-icon-precomposed is the icon just as it will appear, with rounded corners, shadows, etc - pre-rendered (-precomposed) obvious, right?
By the way, we're talking about the value in HTML meta tags here...
