Hey guys. Tomorrow is the big day. Finally going to get a 15" rMBP . 512GB model though, 1TB SSD is quite over kill and would rather save the difference there and get AppleCare. That being said, by what I've read on these forums as well as the Apple discussion boards are three big things. 1. Yellow-ish screens 2. Image Retention 3. Creaking by the trackpad That being said... how should I go about verifying that my new rMBP is within acceptable standards for me? For yellow-ish screen testing I was thinking of just comparing it to a floor model that I deemed "acceptable". For image retention I was planning on using the oh-so popular site: http://www.marco.org/rmbp-irtest.html For creaking I was just planning on placing it on a flat surface, then looking like a crazy person and put my ear to the trackpad area as I pushed down. Is there anything else I'm missing that I should be on the lookout for? Even with the educational discount, I'd like to be fully content with my rMBP considering I'll be dropping a good chunk of change down. Thanks guys!
