Hi all, I just received my rMBP today (my first ever mac device) and i'm absolutely loving it. So far i've tested the machine for image retention, backlight bleeding, dead pixels and the sound system. Is there anything else I should be testing? Also, I had interesting observation. I compared my rMBP (LG display) alongside my sis' cMBP which has a Samsung display and to my surprise, her display had yellowish tint while mine was much 'whiter'. Since i don't have a rMBP with Samsung display, i can't imagine how it will fare against it but i've always thought LG display are more on the yellowish side until I compared it with my sis' cMBP. Cheers!
