I want to get an idea of the likelihood of getting a good panel on the new 13" rMBP. I exchanged my first one because it had yellowing along the left side of the screen, which became very distracting while reading anything on white. My second unit has a similar issue on the bottom half the screen. I've tried to ignore this, but it's pretty obvious when scrolling through text. I've seen plenty of 15" rMBPs over the past year with near perfect uniformity so this has been pretty disappointing. One of the main things I want to do with my computer is read a lot of PDFs and eBooks. Is it true that LG is the only supplier for the 13"? If so I guess they have trouble meeting the demand while having good QC.
