hi mike,
ha - well, i wasn't going to bring it up. i've been trying to get a fix for the video out / flickering picture some of us...ahh, you can search for that one if ur interested.
anyway - so ya, i also had and HAVE that problem.
same thing as you - went outside with it, noticed smudges behind the screen. it was well within my 14 days and i was already ****** about the external screen flicker - i took it back.
the genius saw the prints...and exchanged my machine for another. we checked it in the store and all seemed okay - but alas, i have a finger print on the left side - near the bezel, bout 3/4's the way up.
i've seen videos on youtube...the disassembly ones - there's one where i see the guy remove the glass. looks like a pain in the *** to get to, i can tell you it would be tough...i've taken my machine apart already to align the lid (ANOTHER issue that was driving me crazy).
so now my machine is still flickering on external displays (thru my kvm). the lid now fits perfect and the finish seem to be cool (no dents) - all except for that **** fingerprint.
it's obvious to me that apple has no quality control on these machines and your chances of getting a "perfect" computer are questionable. return it for one issue only to have another raise it's ugly head.
for those of you who are gong to say..."my screen is perfect"...i'd hold off on that statement. take a flashlight - do this indoors, with your screen off - normal room lighting is fine. shine the flashlight at the screen and look - might be in for a surprise.
then again, ignorance is bliss...i wouldn't check if i were you. 🙂
good luck man,
-dave
