about three weeks ago, i sent in my 1.25 albook to have the screen replaced due to a whitespot. now, a "U" shaped mark is appearing on the screen. clearly, i'll be sending it out again to have the screen replaced. does anyone know if apple finally has a permanent fix for this? i know that the spots have been attributed to the top case pressing on the screen. has anyone asked to have this part of the case replaced, as a possible fix? i know that they didn't replace the case part before, as it still had all of its blemishes. thanks.
