Oh, I was actually talking about rearranging, not deleting. The scenario that the storage page supports is actually much different from the ones that the "wiggly icons" supports. Wiggly icons are for deleting apps the user doesn't want and rearranging the icons according to preference. The storage page is for reclaiming storage. The behavior is similar, but the root user desire is somewhat different, which is why it's in a separate place with different information provided.
You can rearrange icons in iTunes. The "wiggly" interface us completely redundant. I agree it is not discoverable; I've had to show each of my kids. It just isn't a comparable example.
I would put the original MacOS eject behavior as much closer. That was horrible.
Hmm, I think of the iTunes interface as an affordance for the awkwardness of the wiggly icon interface, rather that its discoverability. But I suppose it is more discoverable as well.
The old MacOS eject behavior was indeed horrible. It was a miderable design. I can't understand how anyone ever thought "throw the floppy away" was a reasonable abstraction for "eject".
