Well...this is odd. I've my iPad 4 for several months, while reading this post I try one of the tests, and guess what? obviously some IR "manifested" (you know, because of the ghosting thing, hehe

).
Never, never in normal use I've perceived it. And I use the iPad mostly for reading and seeing videos. The image persisted for 10-15 seconds. Honestly - at least in the iPad 4 - it's absolutely no problem in normal use.
<sarcasm> - So...it may get worst over time...aha...like, you know...30 seconds if I let the static image again?...sure, because I've done that so much times in the several past months. </sarcasm>
I've just purchased a rMBP and was worrying about the IR issue. It's not an iPad 4, I get that. But basically it's the same problem. Unless it's really bothering me in normal use I won't even test my screen for problems. I hate dead pixels or uneven lighting, but this issue (at least for me) has proven to be something less than an odd behavior.
But what if de rMBP develop some monstrous ghosting in the next months EVEN in normal use?...if (and only IF) it gets to that point, there's warranty for that. I've used it 2 or 3 times in the past on other Apple products, I KNOW APPLE PRODUCTS ARE NOT ALWAYS PERFECT and that's why warranty exists.
But what if that happens in 2 and a half year? Well...either I've already buy AppleCare and...no problem, or in the event I haven't...well, "bad luck bruh! **** happens" save A LOT of bucks and get it fix if you need it. There's a solution.
But...what if that happens en 5 or 7 or 30 years?... get serious, you aren't one of those guys that want to live forever...are you?
