My retina macbook pro came today and honestly it is running like a charm, no issues whatsoever. It has 2.6ghz CPU, 16gb of RAM and 512GB of Flash Storage. I have installed the Adobe CS6 Masters Collection and it runs it amazingly fast. The UI with Mountain Lion has no lag and safari can scroll through any page without any lag. I would highly recommend this laptop to anyone. I will report if there are any problems or if it is still flawless in a weeks time but by the first day i am impressed.
