Just thought i'd post a few of my initial impressions of my 13" rMBP. Screen - The one i received ended up with a perfect screen. No dead or stuck pixels and very even backlighting. I scaled the resolution up to the highest option (more space) and it's perfect for the screen size. I"m not sure how to replicate the issue of the 15" ghosting, but if someone could explain it I'm glad to give it a try. Performance - Haven't used it much but I purchased the 15" rMBP back when it launched and i noticed even using safari lagged on the 15" (higher scaling than the 13"). With the 13" rMBP i've noticed no lag what so ever on the highest scaling setting. When maximizing Safari to full screen mode, the animation is very smooth. I think the 15" might of been a software issue, but i remember it being pretty bad. If you would like me to try any applications or tests let me know. Size - I returned my 15" soon after purchasing it because I wanted something a little more mobile. I was coming from a 13" air so it was quite a jump. I can say that the 13" rMBP is perfect for those who want a little more power and much better screen when coming from a 13" air. It also seems the bezel around the screen is smaller than the non retina pro 13" which I think makes it more aesthetically pleasing. Overall Quality - Unlike my iPhone 5, this one is pretty much perfect. Only annoyance is the touchpad click is a little louder than i'm used to. Other than that, it's great. The 13" rMBP obviously isn't for everyone and I know alot of people were upset by the lack of a dedicated graphics card, but I think for most people, it will have plenty of power. And most importantly, the integrated graphics card so far seems to easily handle the highest scaling options.
