My opinion is that they suck. Because they do not (and cannot, largely) re-create the experience and value of Apple's phone, no matter how much they copy its look and feel. Of course a complex device like that has nothing to do with a simple script running a website.
But you don't have any principle objections against them? What tells you this script does not suck in comparison to the real one?
I think it would be fair to claim it is the same thing on a smaller scale, because in both cases, it takes much more resources (and creativity) to come up with the original idea/design than to create a copy.
