Ok quick summary; bought a macbook last year, the polycarbonate one. Over the period of 11 months, I have had case issues 3-4 times, two logic board failures (both replaced in one repair...crazy right?). But I have sent my computer in for only case repairs because everything else seemed to work, I guess apple deemed it necessary to replace my logic board for some reason.... Well anyways, I convinced them that a less than a year old laptop should not be doing this and I would possibly like a replacement, the replacement can even be the same exact one, I just thought mine was a lemon! Well the apple care senior specialist had to review my case and came back to me saying he will approve a new macbook UNIBODY polycarbonate with out a doubt because of all the trouble and frustration i've been going through. He would also have it upgraded to 4gbs of ram because I upgraded my original one. Now the question: Should I sell this new in box polycarbonate unibody coming to my door and buy a aluminum? Or just keep this one; I have some idea that this polycarbonate unibody is a stronger design overall but then again I really don't know.... If someone replies that I cheated apple by saying I want a replacement; think about it before you say it. I even told them I wanted a replacement and it could even be the same exact one I had; nothing less nothing better. Thanks all; this is my first post and I am damn glad its a positive one.
