Theft deterrent?
Well, there *is* one argument on Apple's side (though not the one they put forth according to this article) -- because it is apparently impossible for anyone other than Apple to transplant the screen of one iPhone into another one (due to crypto?), no knowledgeable thief is going to try to nick my phone in hopes of selling it for parts.
I wonder whether there is a path that preserves this property, while still giving third parties some option of repairing iPhones?
