I had this realization this A.M. using my early 2011 13" MBP this A.M. after playing with my RMBP yesterday (still have not completely set it up for work use). It was painful to look at the 13"s display -- and I never had any complaints before. I loved my 13", but now the bloom is off the rose. It was like I developed x-ray eyes and could see every last pixel on every letter on the 13"s screen. Anyone else experience this after using their RMBP?
