I don't see this going anywhere. The whole process is redundant. The money they save using smaller discs, which is negligible, is eaten up by the costs of development and engineering this new product.
As software because even more complicated, it eventually won't even fit on the disc. And who wants to search in their drawers for an adapter?
I love that Apple is detail oriented like this, however I file this one under "if it ain't broke, don't fix it".
