Iil try and make this a long story short i had a bunch of repairs on a cmpr and was determined was best to get a brand new replacement. i asked for a retina and pay extra, 300 more for retina, plus another 300 for the bumped specs, 2.7ghz and 16gb of ram. i got the first replacement, lg screen, looks nice but it made crackling noises, whether from speakers or fan i dont know. sounds like exactly like this:http://www.youtube.com/watch?v=rx7Nwp9SE74 the issue started 3 hours after owning it, but it stopped a week later and didnt return 4 days later. i reported the issue and apple sent another. their policy for a replacement computer was to fix it but managed to budge for a new one since i only had it for 3 hours. got the second one, it was a samsung screen. i compared the 2 and the lg looked a little nicer, with a more whiter "white" which i kinda prefered. (either way i suppose iil get use to either screen) the samsung one has a hairline scratch on the back black hinge which should i keep? the lg is essentially perfect the crackling stoped, but maybe it might come back in the future? thanks for your input !
