I checked out the Retina at an Apple store and compared it to the non-Retina MBP with the glossy screen by turning both screens to face the door (it was bright outside). There is a big difference. I don't know about 75% less, but it's very noticeable. I still wish they had a matte option, but I ordered one fully loaded and maxed out anyway. Need the USB3 and 2nd TB port. HDMI out is a nice bonus. Also wish it had 3 USB ports instead of just 2.
