So I was browsing Safari today on my iPad, and I noticed what looked to be 'burn-in' lines on my screen ... along the bottom and along the top going horizontally across the screen. Pretty faint, but I know they are there so I will see them. Honestly, I don't even use my iPad that much, just some light browsing here or there, so I don't know how this even happened. Any ideas on what to expect if I bring it to the Apple store? Will they tell me I'm SoL? Or offer to replace the iPad or the screen?
