I have a relatively new 15" rMPB. The retina display just is not living up to what everyone said it would and should be. Powerpoints and webpages seem somewhat blurry and just not sharp. I read where I should go into the get info of a program and deselect "open in low resolution" however that option is greyed out in applications. I'd like to think this is a user error and not a equipment issue. Here is an example of a PPT I was just reading this morning... thanks in advance... now off to a test. YAY.
