This post is not to bash the rMBP in anyway. It is the most incredible computer I'ver ever owned and I have a truly flawless Samsung screen. However I noticed after working instant hours on the rMBP I am getting migraines and feeling dizzy like seasick. It may sound stupid, but could it be that the Retina display gives to much information/sharpness that the brain has to work to hard? Anyone else feel the same symptoms?
