Query: Can't use Shuffle lanyard when using this skin.

What this product description doesn't mention is that you must use the included Speck USB cap when using the Skin Clear. The ball-bearing mechanism of the standard Shuffle USB caps do not engage when the Skin Clear is installed on the Shuffle. Since the Speck USB cap does not have a lanyard string, you're out of luck if you use the lanyard as I do.
