Same. The first one was perfect except for a piece of dust under the screen, but my 2 subsequent white box replacements both had interlaced screens and ironically my current one has a dead/hot pixel in the same spot as the dust on my first one.
I called Apple care and they said to keep going to Apple Stores to try while Apple Stores say they can only open 2 boxes for me and told me to call Applecare...
