"I can never ever open iPad keyboard more for than 5 minutes without getting a burn-in since the first day since I bought it." Could you clarify what you mean

  iPad on-screen keyboard. The burn-in is very noticeable after few minutes especially in landscape mode (for some reason).

    That's not how burn in works ... Burn in requires a static image for a long period of time (months/years). It doesn't just magically show up after 5 minutes of use.

      Sounds like he's referring to "image persistence", which is similar in appearance to burn-in, but a different mechanism. Burn-in is more likely to be found on CRTs and can take a long time to occur. Image persistence can happen in seconds or minutes and is what is seen on LCDs. It's usually temporary or reversible. (And plasma owners can experience both, yay! :)

        Hmm, you're right. I did choose a wrong word, my problem is more of Image Persistence[1][2] than CRT-type burn-in, which in my case, did magically appears after few minutes of use and took a long time to disappear. This doesn't deny my point of Apple support is awful outside US, though. I also have issue with horizontal line on 2009 iMac screen that they refuse to acknowledge the problem until very recently (October 2011). I'm happy that it's finally fixed, but it shouldn't took two years.
