I've been laptop-only for the last couple of years, so I can't really provide the answer you're looking for.

I generally purchase AppleCare for anything that has a screen on it, though, and Apple's always been fantastic about no-hassle resolutions to any trouble I have had. Including the time I walked in and said "I dropped my phone; I need to buy a new screen"; when the face sensor didn't work with the new screen attached, they replaced the whole thing at no cost.

Again, not really the answer you're looking for, but hopefully at least minimally helpful. :-)
