I'm getting embarrassed of going to the apple store. I absolutely love my iPad, but I keep having problems. First, I had drip marks on the screen (oleophobic coating was messed up). Apple replaced it. Then, dust was under the screen. Apple replaced it. Now, there's a stuck pixel that I cant unstick. Should I take it in yet again? Does an iPad without defects exist? I'm thinking about just returning it...although I love it, at this point it's giving me more stress than happiness.
