Obviously the MBPR has a "retina" display. I recently picked up a 2015 MBA 13" for a killer deal from BB when they had them on clearance. One thing i noticed compared to having a MBPR in the past. The font sizing is a lot smaller compared to the "retina" setting they have on the MBPR. I have downloaded the plugin all pages zoom, and have been running the font at 106% like someone suggested. Does anyone know what size i would have to run to get the the same sizing found on the 13" MBPR? Other than that i have been pleased even though its a TN panel. I downloaded a custom color profile to calibrate the display and REALLY helped the contrast and color. Looks night & day. The Command + seems to get it close to how the MBPR is shipped, but you have to do that command overtime you fire up Safari. I find when you zoom in on the text it makes it less jaggy too. But with the command + overtime it switches pages it flashes the old size, and than adjusts to the new. A tad annoying but i guess i would have to live with that?
